VS1063a HW Guide7 HARDWARE REGISTERS7.11 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 lowerthan the DAC samplerate, aliasing may and will occur.7.11.1 SRC RegistersResampler SRC registersReg Type Reset Abbrev[bits] Description0xC046 rw 0 SRC_CONTROL[12:0] SRC control0xC047 r 0 SRC_DATA_LEFT SRC left channel data0xC048 r 0 SRC_DATA_RIGHT SRC right channel data7.11.2 Control SRC_CONTROLSRC_CONTROL BitsName Bits DescriptionSRC_ENABLE 12 Set to enable SRCSRC_DIV 11:0 Set samplerate to XTALI/2/(SRC_DIV+1)7.11.3 SRC InterruptsEach time a new (stereo) sample has been generated, an SRC interrupt is generated.Version: 1.02, 2012-12-05 26
