Slot 4: Right Channel PCM Capture Data
Slot 4 contains the right channel data. The 20 bits of this slot are defined as:
F76 F77 F78 F79 F80 F81 F82 F83 F84 F85 F86 F87 F88 F89 F90 F91 F92 F93 F94 F95
Bit 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
RP17 RP16 RP15 RP14 RP13 RP12 RP11 RP10 RP9 RP8 RP7 RP6 RP5 RP4 RP3 RP2 RP1 RP0 0 0
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.
