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
