Table 22-4. Interaction Between RSIZE and CM Bits
RSIZE
Copyright 2007 Cirrus Logic
Compact mode enable. If the RSIZE value is either “00” or
“11” (setting the data word size to 12- or 16-bits) then the
CM bit determines whether the two data words are
compacted into one 32-bit word, or each is sent in a
separate word. If the RSIZE value is either “01” or “10”
(setting the data word size to 18- or 20-bits) then the CM
bit has no effect. See
0 - The data is justified into one 32 bit word
1 - The two data words are compacted into one 32-bit
word for reading by the CPU.
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 contains SLOT2 data (only use if sampling rate is
48 kHz). Takes precedence over AC97S2Data.
