ADC_WLEN
Address: 0xC0 (192)
Type: R/W
Software Reset: 0x0F
Hardware Reset: 0x0F
To select ADC word length AWL4 through AWL0 bits can be used.
This 5 bit value must contain the size of the significant data bits minus one.
ADC_WPOS
Address: 0xC1 (193)
Type: R/W
Software Reset: 0x00
Hardware Reset: 0x00
These bits specify the position of the sample word referred to the LRCK slot boundary.
Bit AWP0 thru AWP4 must be programmed with the number of bits to ignore after the sample word.
ADPCM_SKIP_FRAME
Address: 0xC2 (194)
Type: R/W
Software Reset:0x00
Hardware Reset: 0x00
This register is useful when decoding ADPCM frame-based streams in order to skip the specified number
of frames.
The content of the register will automatically be decremented on each new frame and the skip process will
continue until the content reaches zero.
