Preliminary Version 1.3 Dot Matrix LCD Controller RAiO TECHNOLOGY INC. www.raio.com.tw 10/46 RA6963 6. Functions Description 6-1 Functional Definition ‹ After power on, it is necessary to reset. The RST is kept Low between 5 clocks up (oscillation clock). ‹ When HALT = Low, the oscillation stops. The power supply for the LCD must be turned off, to protect the LCD from DC bias. ‹ The HALT function( HALT = Low) includes the RESET function(RST =Low). ‹ The column/line counter and display register are cleared by RST . (Other registers are not cleared.) Disable the display using the clear-display register ‹ The status must be checked before data or comm ands are sent. The MSB=0 status check must be done in particular. There is a possibility of erroneous operation due to a hard interrupt. ‹ STA0 and STA1 must be checked at the same time. When a command is executed, data transmission errors may occur. ‹ The RA6963 can only handle one byte per machine cycle (16 clocks). It is impossible to send more than two data in a machine cycle. ‹ When using a command with operand data, it important to send the data first, and then executes the command. ‹ The character fonts used by the RA6963 are different from ASCII codes. 6-2 State After RESET/HALT < Table 6-1 > Pins HALT RESET SD[7:0] Floating Floating D[7:0] Floating Floating MRW Hi Hi MCE Hi (Note 1) Hi (Note 1) A[15:0] Hi (Note 2) Hi (Note 2) 0CE , 1CE Hi (Note 1) Hi (Note 1) ED, HOD Final data Final data HSCP Low Low LP Low Low CDATA Hi Hi FR Hi Hi CH1 Low Test Signal CH2 Low Test Signal DSPON Low Low X2 Hi OSC Clock Note 1 :In Attribute mode, Hi or Low according to state of graphic pointer Note 2 :In Attribute mode, data to graphic pointer

Preliminary Version 1.3 Dot Matrix LCD Controller RAiO TECHNOLOGY INC. www.raio.com.tw 11/46 RA6963 6-3 Row / Column and Oscillation Clock The frequency of the crystal oscillator is adjusted by the following formula. fOSC : Frequency of oscillation fSCP : Frequency of shift clock (fSCP = fOSC / 2 ) fR : Frequency of Frame M : Number of characters on one line (number of dots on one line =8M) For all font sizes (e.g. 7 x 8, 7 x 8, 5 x 8) the oscillation frequency remains constant. N : Number of rows (Duty=1/8N) fSCP x 8N= 1 fR fOSC = fR x 64 x 2 x M x N (fR = 60Hz) < Table 6-2 > Unit: MHz M N 32 40 64 80 Duty Upper 0.492 0.614 0.983 1.229 2 Lower 0.983 1.229 1.966 2.458 Note 1: Upper Æ Single-Scan.

Preliminary Version 1.3 Dot Matrix LCD Controller RAiO TECHNOLOGY INC. www.raio.com.tw 12/46 RA6963 6-4 RAM Interface The external RAM is used to store display data (text, graphic and external CG data). With single-scan, text data, graphic data and external CG data can be freely allocated to the memory area (64 KB max). With dual-scan, LCD-I is allocated to 0000h to 7 FFFh (32 KB max), LCD-II is allocated to 8000h to FFFFh (32-KB Max). Text data, graphic data and external CG data can be freely allocated in LCD-I. In LCD-II, the same addresses must be allocated as in LCD-I, except A15. A15 determines selection of LCD-I or LCD-II. It can be used the address-decoded signals 0CE (0000h to 07FFh), 1CE (0800h to 0FFFh) within 4 KB. 0CE and 1CE allow decoding of addresses in the ranges (0000h to 07FFh) and (0800h to 0FFFh) respectively within a 4-KB memory space.

Preliminary Version 1.3 Dot Matrix LCD Controller RAiO TECHNOLOGY INC. www.raio.com.tw 13/46 RA6963 6-5 Communications with MPU 6-5-1 Status Read A status check must be performed before data is read or written. Status Check The Status of RA6963 can be read from the data lines. < Table 6-3 > RD WR CS C/ D SD[7:0] L H L H Status Word The RA6963 status word format is as follows: MSB LSB SD7 SD6 SD5 SD4 SD3 SD2 SD1 SD0 STA7 STA6 STA5 STA4 STA3 STA2 STA1 STA0 < Table 6-4 > STA0 Check command execution capability 0: Disable 1: Enable STA1 Check data read/write capability 0: Disable 1: Enable STA2 Check Auto mode data read capability 0: Disable 1: Enable STA3 Check Auto mode data write capability 0: Disable 1: Enable STA4 Not used STA5 Check controller operation capability 0: Disable 1: Enable STA6 Error flag. Used for Screen copy commands. 0: No error 1: Error STA7 Check the blink condition 0: Display off 1: Normal display Note 1: It is necessary to check STA0 and STA1 at the same time. There is a possibility of erroneous operation due to a hardware interrupt. Note 2: For most modes STA0 /STA1 are used as a status check. Note 3: STA2 and STA3 are valid in Auto mode; STA0 and STA1 are invalid.

Preliminary Version 1.3 Dot Matrix LCD Controller RAiO TECHNOLOGY INC. www.raio.com.tw 14/46 RA6963 Status Checking Flow STATUS STA0=1 STA1=1 NO RETURN YES AUTO MODE STATUS (*1) NO RETURN YES (*1) STA2=1 (Read) or STA3=1(Write) < Figure 6-2 > Note 4: When using the MSB=0 command, a Status Read must be performed. If a status check is not carried out, t he RA6963 cannot operate normally, even after a delay time. The hardware interrupt occurs during the address calculation period (at the end of each line). If a MSB=0 command is sent to the RA6963 dur ing this period, the RA6963 enters Wait status. If a status check is not carried out in this state before the next command is sent, there is the possibility that command or data will not be received.

Character code 00h to 80h assign External character generator, when External generator mode. The senior five bits define the start address in external memory of the CG RAM area. The next eight bits represent the character code of the c haracter. In internal CG ROM mode, character Codes 00h to 7Fh represent the predefined “internal” CG ROM characters, and codes 80h to FFh Represent the user’s own “external” characters. In external CG RAM mode, all 256 codes from 00h to FFh can be used to represent the user’s own characters.

The display mode does not change until the next command is sent. The logical OR, EXOR, AND of text or graphic display can be displayed. In internal Character Generator mode, charac ter codes 00h to 7Fh are assigned to the built-in Character generator ROM. The character codes 80h to FFh are automatically assigned to the external character generator RAM. (Example) Graphic Text < Figure 6-7 > Note: Attribute functions can only be applied to text display, since the attribute data is placed in the graphic RAM area. Attribute Function The attribute operations are Reverse display, Char acter blink, bold and Inhibit. The attribute data is written into the graphic area, which was defined by the Set Control word command. Only text display is possible in Attribute Function mode; graphic display is automatically disabled. However, the Display Mode command must be used to turn both Text and Gr aphic on that in order to for the Attribute function available. The attribute data for each character in the text area is written to the same address in the graphic area. The Attribute function is defined as follows.

This command is convenient for sending a full screen of data from the external display RAM. After Setting Auto mode, a Data Write (or Read) command does not need sent between each datum. A Data Auto Write (or Read) command must be sent after a Set Address Pointer command. After this Command, the address pointer is automatically incremented by 1 after each datum. In Auto mode, the RA6963 cannot accept any other commands. The Auto Reset command must be sent to the RA6963 after all data has been sent, to clear Auto Mode. Note: A Status Check for Auto Mode STA2, STA3 should be checked between sending of each datum. Auto Reset should be performed after checking STA3=1 (STA2=1). Refer to the following flowchart.

Preliminary Version 1.3 Dot Matrix LCD Controller RAiO TECHNOLOGY INC. www.raio.com.tw 45/46 RA6963 < Figure 9-3 > All LCD require two power sources, VDD for logic ci rcuits and VEE for Liquid Crystal (LC) drive. Some graphics LCD modules will run directly of a single VDD supply by generating the VEE voltage on-board; others will require an external DC-DC converte r to generate the negative VEE voltage.
