7 FUNCTION DESCRIPTIONS

7.1 CPU

GPC71XXXA features a 4-bit RISC CPU , executing the 12-bit instruction set with total of 72 instructions available, 7 stacks managed by a 3-bit stack pointer, three DPRs(Data Pointer to read ROM) sharing stack 4 ~ 6, and two VPRs(Voice Data Pointer) for SPU.

7.2 Memory

7.2.1 SRAM

There are 256 nibbles of SRAM, grouped into 4 banks . Each bank has 64 nibbles and supports index mode to read/write its content addressed by TXR.

7.2.2 OTP

GPC71XXXA is equipped with 680K/ 340K/ 160K/ 128K/ 96K/ 64K/ 32K x 12-bit factory programmed OTP memory.

7.3 Clock Source

Clock source is an inner resis tance oscillator with CPU clock options of 1MHz or 2MHz

7.4 Low Voltage Reset

With the LVR function, a reset signal is generated to reset system when the operating voltage drops below LVR level.

7.5 Interrupt

An interrupt is a special event request to microcont roller. When it occurs, the corresponding interrupt will activate and direct the program code to execute the respective functions. The GPC71XXXA has 5 interrupt sources . Please refer to programming guide for more details.

7.5.1 Timebase

There are two Timebases, TB1 and TB2, generated by the system clock. The interval of TB1 is allowed up to 1ms and TB2 allows up to 2ms.

7.6 SPU

One channel SPU supports MIDI playback with A3400Pro -like decode or PCM format, and each channel has an 8-bit envelope control.

7.7 PWM

The PWM module consists of a 14-bit PWM driver to drive speaker directly.

7.8 Sleep Mode, Wakeup and Watchdog

7.8.1 Sleep mode and wakeup

Sleep mode or known as power down mode is an operating state that requires an extremely low power consumption to maintain the system in active. The sleep mode is particularly useful for the application areas where the system is required to constantly maintain its bas ic functionality and where the power capacity is limited. GPC71XXXA enters sleep mode when SLEEP instruction is executed and can be woken up by interrupt or key state change. CPU will continue to execute the rest of program code from where it entered sleep mode.

7.8.2 Watchdog Reset

A watchdog reset is a reset signal that is generated to reset the entire system when watchdog counter is overflow. In case when the program code has been running into a n unknown state and without the watchdog signal being cleared for a certain period of time, watchdog function automatically generates a reset signal pulling the system back from unknown state.

7.9 I/O

The GPC71XXXA features 16-bit or 8 -bit programmable Input/output pins and many of them feature wakeup capability. These IOs normally support input function with floating or pull-low and output options. In addition to the ordinary I/O function, some IO ports have special functions. The following table summarizes the special functions for these IOs. Special Function in Port Port Special Function Function Description Note IOA0/IOB0~IOD0 Key Reset Key reset pin, configurable through code option High active; IOC0/IOD0 isn’t supported in GPC71032A/GPC71016A IOA1/IOB1~IOD1 IROUT IR carry output, configurable through code option IOC1/IOD1 isn’t supported in GPC71032A/GPC71016A IOA2/IOB2~IOD2 EXT INT External interrupt input, configurable through code option IOC2/IOD2 isn’t supported in GPC71032A/GPC71016A

9 APPLICATION CIRCUITS

9.1 Light Loading and Circuit without Noise

PCB Layout Guidelines: 1. PVDD may be greater than or equal to VDD. 2. VSS and PVSS must be connected to ground input directly, not the branch of each other. 3. When using two batteries, 0.1uF ~ 4.7uF is suggested for C1, and it should be increased in a high volume application. 4. IOC/IOD isn’t supported in GPC71032A/GPC71016A. 5. There is no “TEST” pin in GPC71032A/GPC71016A. GPC71XXXA

9.2 Heavy Loading or Circuit with Noise

PCB Layout Guidelines: 1. PVDD may be greater than or equal to VDD. 2. VSS and PVSS must be connected to ground input directly, not the branch of each other. 3. A typical value of C1 is 47uf, and it should vary in different loadings. 4. If there is application with motor, REGOUT should be connected with C4. 5. IOC/IOD isn’t supported in GPC71032A/GPC71016A. 6. There is no “TEST” pin in GPC71032A/GPC71016A. GPC71XXXA
