Description
‘0’ = the power bridge is in fault condition
‘1’ = the power bridge is in normal condition
‘0’ = normal operation
‘1’ = CRC error on DRC BIQUADS
‘0’ = normal operation
‘1’ = CRC error on BIQUADS
‘0’ = normal operation
‘1’ = PWM outputs are invalid
‘0’ = normal operation
‘1’ = SAI interface error detected (see
Configuration register B (addr
‘0’ = PLL is locked
‘1’ = PLL is not locked
Description
0000: 44.1/48 kHz BITCLK = 64 Fs
0001: 32 kHz BITCLK = 64 Fs
0010: 96 kHz BITCLK = 64 Fs
0011: 48/44.1/32 kHz MCK = 256 Fs
others: clock configuration depends on IR/MCS bits
‘0’ = SAI configured in I
‘1’ = SAI configuration depends on CONFB register
