Notes for MFP1:
ADC_CLKSEL selected in REG 8, default is ADC_MCLK.
PAIFTXMS_CLKSEL selects PLLACLK if PAIF sources SPDIF Rx, otherwise PAIFTXMS_CLKSEL selects ADC_CLK
(register 8)
3. MFP2 usage can be described as follows:
IF
(ADC_CLKSEL ≠ ADCMCLK)
AND
(TX_CLKSEL ≠ ADCMCLK)
AND
(SAIFMS_CLKSEL ≠ ADCMCLK) THEN
MFP2 = GPO2;
ELSE
MFP2 = ADCMCLK;
