DESCRIPTIONS
-
Register index. The R_INDEX[6:0] echo the register index (address)
when a register read has been requested in the previous frame.
The R_INDEX[6:0] bits are read only
Slot request. The bits indicate if the external codec need new PCM
data that will transfer in next frame.
Any bit in SLOT_REQ[1:0] is set to 1, indicate external codec does
not need a new sample in the corresponding slot[3:4] of the next
frame
Any SLOT_REQ[1:0] is clear to 0, indicate external codec need a
new sample in the corresponding slot[3:4] of the next frame
The SLOT_REQ[1:0] bits are read only
