11.16 Resampler SampleRate Converter (SRC)
The resampler SRC makes it possible to catch audio from the DAC path.
Note: hardware makes no attempts at low-pass filtering data. If the SRC samplerate is lower
than the DAC samplerate, aliasing may and will occur.
Resampler SRC registers, prefix SRC_
Reg Type Reset Abbrev[bits] Description
0xC046 rw 0 CONTROL[12:0] SRC control

0xC048 r 0 DATA_RIGHT SRC right channel data
SRC_CONTROL Bits
Name Bits Description
SRC_ENABLE 12 Set to enable SRC
SRC_DIV 11:0 Set samplerate to XTALI/2/(SRC_DIV+1)
