Slot 4: Right Channel PCM Capture Data
Slot 4 contains the right channel data. The 20 bits of this slot are defined as:
RP17 - RP0 - This is the 18-bit PCM 2’s compliment capture data from the right channel ADC in the
CS4297. The PCM capture data is left justified in the most significant 18 of the 20 bits in the slot.
The least significant 2 bits will be ‘cleared’.
Slots 5 through 12 are not implemented in the CS4297, and therefore will always be returned ‘cleared’ for
all bits.
