// Set the PLL dividers
Int_Divisor = floor(PLL_Output_Freq/Sys_MCLK_Input_Freq)
Frac_Divisor = ((PLL_Output_Freq/Sys_MCLK_Input_Freq) - Int_Divisor)*2048
Modify CHIP_PLL_CTRL->INT_DIVISOR Int_Divisor
Modify CHIP_PLL_CTRL->FRAC_DIVISOR Frac_Divisor
Input/Output Routing
To avoid any pops/clicks, the outputs should be muted during these chip configura-
tion steps. Refer to section 6.2.6 for volume and mute control.
A few example routes are shown below:
// Example 1:
// Route I2S_IN to DAP
Modify CHIP_SSS_CTRL->DAP_SELECT 0x0001
// Route DAP to DAC
Modify CHIP_SSS_CTRL->DAC_SELECT 0x0003
// Select DAC as the input to HP_OUT
Modify CHIP_ANA_CTRL->SELECT_HP 0x0000
// Example 2:
// Set ADC input to MIC_IN
Modify CHIP_ANA_CTRL->SELECT_ADC 0x0000
// Route ADC to I2S_OUT
Modify CHIP_SSS_CTRL->I2S_SELECT 0x0000
// Example 3:
// Select LINEIN as the input to HP_OUT
Modify CHIP_ANA_CTRL->SELECT_HP 0x0001
Digital Audio Processor Configuration
To avoid any pops/clicks, the outputs should be muted during these chip configura-
tion steps. Refer to section 6.2.6 for volume and mute control.
// Enable DAP block
// NOTE:
// sub-blocks are enabled.
Modify DAP_CONTROL->DAP_EN 0x0001
6.2.4.1.
These programming steps are needed only if dual input mixer feature is used.
// Enable Dual Input Mixer
Modify DAP_CONTROL->MIX_EN 0x0001
// NOTE: This example assumes mix level of main and mix
// channels as 100% and 50% respectively
// Configure main channel volume to 100% (No change from input
// level)
DAP will be in a pass-through mode if none of DAP
Dual Input Mixer
I2S_IN -> DAP -> DAC -> LINEOUT, HP_OUT
MIC_IN -> ADC -> I2S_OUT
LINEIN -> HP_OUT
