Figure 7-4 Sample_Project_3 Configuration

The following exlpains the POI VM:
REG2, 0x44)  write 0x44 into reg0x02; enable Decoder and PWM output path;
CFG(
CFG(GPIO_TRIG_CH_SEL_L, 0x24) write 0x24 into reg0x14, assign channel 0 to VM associated with GPIO0;
CFG(GPIO_VOL_UD_SEL, 0xb8) write 0xb8 into reg0x16, GPIO0 Trigger to volume up;
REG_GPIO_OE, 0x30)  write 0x00 into reg0x1A; configure GPIO 0,1,2 and 3 pins as input pins;
CFG(
REG_GPIO_DO, 0x30)  write 0x00 into reg0x19; GPIO4 and 5 output high;
CFG(
REG_GPIO_PE, 0x3F)  write 0x3F into reg0x1B; enable Pull-Enable for GPIO0-5;
CFG(
REG_GPIO_PS, 0x3F)  write 0x3F into reg0x1D; enable Pull-High for GPIO0-5;
CFG(
REG_GPIO_AF1, 0x0F) 
CFG(
REG_GPIO_AF0, 0x00)  write 0x00 into reg0x1F; combined with reg0x1E to confiure GPIO0-3 as
CFG(
R0, 0x08) 
CFG(
R1, 0x04)  write 0x04 into reg0x22; associate VM0x04 with GPI1;
CFG(
R2, 0x05)  write 0x05 into reg0x24; associate VM0x05 with GPIO2;
CFG(
R3, 0x08) 
CFG(
R4, 0x08) 
CFG(
R5, 0x08)  write 0x08 into reg0x2A; associate VM0x08 with GPIO5;
CFG(
 Play VP ―Fastbeep‖
PLAY(FastBeep)
 power down device (to save power).
PD
The Wakeup VM 0x02 enables the playback path for all triggers.
The following explains the custom VM 0x04:
 Play VP ―one‖
PLAY(one)
 power down device (to save power).
PD
R1, 0x06)  write 0x06 into reg0x22; associate VM0x06 with GPI1;
CFG(
LOOP(Sine_0dot5dB_5_Sec_440Hz,0 )  Loop play a sound effect infinitely.
Label1: CFG(CH1_CNTR, 0x10) write 0x10 into reg0x0E, initialize channel counter 1 as 0x10;
REG_GPIO_DO, 0x06) write 0x06 into reg0x19; drive GPIO output pins
CFG(
