(1) The flag SFSOUT[3:0] is output from the register and MPIOs are assigned as SFSOUT[3:0].
'0' or '1' indicates the register output data. The symbol 'H' or 'L' refers to the MPIO output electrical signal.
The Biphase Sampling Frequency Calculator is also used for restricting the type of data that can be received.
1. If Register 27h/MSK128 is set to '1', the PCM9211 does not accept 128-kHz sampling frequency data
2. If Register 27h/MSK64 is set to '1', the PCM9211 does not accept 64-kHz sampling frequency data.
3. If Register 27h/NOMLMT is set to '1', the PCM9211 only accepts the nominal audio sampling frequency
within ±2%.The nominal audio sampling frequencies are 8 kHz, 11.025 kHz, 12 kHz, 16 kHz, 22.05 kHz, 24
kHz,32 kHz, 44.1 kHz, 48 kHz, 64 kHz, 88.2 kHz, 96 kHz, 128 kHz, 176.4 kHz, and 192 kHz.
4. For Register 27h/HILMT[1:0] and Register 27h/LOLMT[1:0]: These registers are used for setting a higher or
lower limit to the acceptable sampling frequency.
Register 21h/RXFSRNG is used for global control of the acceptable sampling frequencies. If normal mode is
selected, the range of acceptable sampling frequency is restricted from 28 kHz to 108 kHz. If wide mode is
selected, the range is from 7 kHz to 216 kHz.
