WORD_LEN=BIT_LEN16
Data control
WORD_LEN | PCM Word Length in number of bits: (Note: These bits are connected to AR36U12.PDM_CORE2_CFG.PCM_IWL) 0 (BIT_LEN16): 16-bit 1 (BIT_LEN18): 18-bit 2 (BIT_LEN20): 20-bit 3 (BIT_LEN24): 24-bit |
BIT_EXTENSION | When reception word length is shorter than the word length of RX_FIFO_RD, extension mode of upper bit should be set. ‘0’: Extended by ‘0’ ‘1’: Extended by sign bit (if MSB word is ‘1’, then it is extended by ‘1’, if MSB is ‘0’ then it is extended by ‘0’) |
