DAOSR
DAC oversampling ratio. This bit cannot be set for 64× when CONVSR[2:0] is set to 96 kHz.
0 = 128× (default).
1 = 64×.
3
ADOSR
ADC oversampling ratio. This bit cannot be set for 64× when CONVSR[2:0] is set to 96 kHz.
0 = 128× (default).
1 = 64×.
[2:0]
CONVSR[2:0]
Converter sampling rate. The ADCs and DACs operate at the sampling rate set in this register. The converter rate
selected is a ratio of the base sampling rate, fS. The base sampling rate is determined by the operating frequency
of the core clock. The serial port mirrors the converter sampling rates set in this register.
