Table 22-3. Interaction Between RSIZE and CM
RSIZE
Copyright 2007 Cirrus Logic
Determines how many bits to a data word. See
for details of the interaction between RSIZE and CM.
00 data is 16 bits
01 data is 18 bits
10 data is 20 bits
11 data is 12 bits
FIFO stores SLOT12 data (takes precedence over
AC97S12Data)
FIFO stores SLOT11 data
FIFO stores SLOT10 data
FIFO stores SLOT9 data
FIFO stores SLOT8 data
FIFO stores SLOT7 data
FIFO stores SLOT6 data
FIFO stores SLOT5 data
FIFO stores SLOT4 data
FIFO stores SLOT3 data
FIFO stores SLOT2 data
FIFO stores SLOT1 data
A “1” written to this bit enables the receive for this FIFO
and enables the PCLK for the respective channel.
