The S5A1901H02 receives commands and parameters in serial format from microcontroller through built-in HIU. The data must be in byte unit (8 bit). The host commands are composed of the following three types.
- Command Only
- Command followed by Parameter
- Command followed by Parameter #1 (high byte) followed by Parameter #2 (low byte) The details on commands used in the S5A1901H02 can be found in Chapter 4. The HIU supports either normal microcontroller interface or I 2 C bus interface. In normal host interface, the related pins are HCLK (Normal Host Interface Bit Clock), HWEB (Normal Host Interface Write Enable) and HDATA (Nor- mal Host Interface Data In/Out). In I 2 C bus interface, the related pins are SDA (Serial Data Line), SCL (Serial Clock Line) and SAS (I 2 C Bus Interface Programmable Slave Address Selection). One can refer to I 2 C Bus Specification by Philips. The I 2 C bus interface in the S5A1901H02 operates in Slave-Transmitter mode. The other function of HIU is the spectrum request function. The spectrum value is sent to microcontroller. The maximum bit clock (HCLK or SCL) is 400kHz. Note that since the chip is being initialized for at least 1ms after reset, commands should be transferred to the chip after 1ms.
Figure 7. Data Format in Normal Host Interface
S5A1901H02 AUDIO EFFECT PROCESSOR System Clock In the S5A1901H02, there are two ways to supply the system clock,
- Using Clock Doubler The CLKS should be set to LOW and X-tal oscillator of 16.9344MHz is connected to XI and XO pins. Then, the clock doubler doubles 16.9344MHz to 33.8688MHz and outputs to MCLK.
- Using External Clock Source The CLKS should be set to HIGH. In this case, the MCLK pin is the input which is the system clock of 33.8688MHz. Reset The S5A1901H02 provides hardware reset and software reset. In hardware reset using RESB pin, the reset signal has to be kept for L/R one cycle pulse width (approx. 22.67 µs) for stable initialization of built-in codec. In the soft- ware reset (command code: 0x00) through HIU, system initialization is internally processed. Power Down The system power down mode set by host command through HIU disables all hardware macro blocks in the S5A1901H02, i.e., DSP, delay RAM, data RAM, program ROM, glue logic and codec. Every host command can wake-up the system power down mode.
vocal canceller is selected, the audio source whose vocal component is cancelled is bypassed without stage effect. In Karaoke Mode II, the microphone input is echoed by the echo filter 2 and the audio source input is bypassed. Figure 16. Karaoke Mode I, II spread echo which is very impressive.
- The gain parameters, G0 and G1, are used to control left and right input gains respectively.
- The parameters, BL0, BL1 and AL1, are coefficients of the IIR filter used for left prefilter. The parameters, BR0, BR1 and AR1, are coefficients of the IIR filter used for right prefilter. The parameters, BD0, BD1 and AD1 are coefficients of the IIR filter used for postfilter. The structures of all three filters are realized by the first order IIR. The zero of the transfer function of each filter is − BX1 / BX0 and the pole is − AX1, where X is L or R or D.
- The parameters, G2, G3 and G4, are left term gain, right term gain and feed-back term gain respectively.
- The parameters, G5 to G11, are gains of delayed signals in the left channel. The parameters, G14 to G20, are gains of delayed signals in the right channel. The parameters, G12 and G21, are gains of effected output signals. The parameters, G13 and G22, are gains of directed output signals.
- The parameter, T0, is the pointer address of the feed-back signal in the delay memory. The parameter, Tc, is the pointer address of the current input signal. The parameters, T1 to T7, are pointers designating addresses of the 7 different delayed signals. Note that the pointer address is same as the amount of delay. Thus, T0 to T7 values can be simply determined as the amount of delay which one wants to set.

AUDIO EFFECT PROCESSOR S5A1901H02 Movie Mode I, II The Movie Mode I and II create 3-dimensional sound images from 2-channel stereo input signals. The Movie Mode- I enhances stereo images dynamically using the Samsung proprietary TLA (Table Lookup Algorithm) method. One perceives as if he or she is in the live stage. The Movie Mode II uses a sound source relocalization technique based on Head Related Transfer Function (HRTF). Only using two front speakers, one can perceive as sound coming from various directions. Graphic Equalizer The S5A1901H02 provides the graphic equalizer having following features.
- 3/5/7-band graphic equalizer
- 5/7-band spectrum analyzer display
- ± 12dB adjustable range The 3-band graphic equalizer can be used as a simple digital tone control (as bass and treble control). Center Frequencies of Equalizer Bands (Hz) The gain control of each band uses an attenuation table containing attenuation values, which has the size of 25 to implement ±12dB with 1dB step control Band 3-Band Mode 5-Band Mode 7-Band Mode Band0 63 100 63 Band1 1 K 300 160 Band2 16 K 1 K 400 Band3 − 3 K 1 K Band4 − 10 K 2.5 K Band5 − − 6.4 K Band6 − − 16 K

AUDIO EFFECT PROCESSOR S5A1901H02 These parameters are provided for user to design his or her own sound mode. The list of parameters (see Block Diagram for User Defined Mode in Chapter 3.) is one of sound modes provided in the S5A1901H02. In fact, most of sound modes in the S5A1901H02, e.g., hall, super woofer and so on, have similar structure. By changing parame- ters given in Figure , one can obtain completely different sound mode. Loading parameters which are redefined by user can be done in running of any sound mode since the memory site for these parameters does not overlap with that for any other modes. Designed mode after loading all parameters to DSP is defined as User Defined Mode. To run this mode, simply select the command code 0x13 (see Command for Mode Selection).

AUDIO EFFECT PROCESSOR S5A1901H02 NOTIFICATION FOR MICROCONTROLLER PROGRAMMING Fade-in/ Fade-out: To avoid noise due to abrupt change of signal, hardware configuration or filter coefficients, the fade-out and fade-in processes in the S5A1901H02 happen in following situations.
- Change sound mode
- Change equalizer mode
- Change hardware configuration related to “ Digital data format and Input configuration ” .
- Change “ Source selection in Karaoke mode I ”
- “ Vocal Canceller ” is turned on or off
- “ Loudness Function ” is turned on or off
- “ Mixing Function ” is turned on or off
- “ Bypass On-chip Function ” is turned on or off
- “ Output channel selection ” is turned into reversion from normal, or vise versa. The time for finishing fade-out and fade-in processes needs about 0.9 ms for sound mode change and about 0.4 ms for other cases. Note that the S5A1901H02 denies process of any function received from microcontroller during fade-out or fade-in process. Sound Mode Selection:
- When one of Karaoke modes is selected, “ Bypass On-chip Function ” or “ Mixing Function ” is automatically turned off if one of them is turned on and “ Source selection in Karaoke I ” is set to normal. Thus, the microcontroller should change the status of “ Mixing Function ” , “ Bypass On-chip Function ” and “ Source selection in Karaoke I ” at this time. Note that “ Source selection in Karaoke I ” can be inverted only in Karaoke mode I. Equalizer Mode Selection:
- Equalizer modes and loudness function are exclusive, and thus, equalizer mode cannot be selected while loudness function is working. To select equalizer mode, the loudness function should be turned off first. Vocal Canceller:
- Movie modes do not work with this function. In S5A1901H02, this function is ignored in one of Movie modes. Thus, if the sound mode is one of Movie modes, the microcontroller dose not make this function to be selected.
