3.1.3
Command Data Port (Slot 2)
WD[15:0]
Write Data. The WD[15:0] bits contain the 16-bit value to be written to the register. If an ac-
cess is a read, this slot is ignored.
NOTE:
For any write to an AC
97 register, the write is defined to be an
atomic
access. This means
that when the Slot 1 Valid bit in output Slot 0 is
set
, the Slot 2 Valid bit in output Slot 0 should
always be
set
during the same audio frame. No write access may be split across 2 frames.
3.1.4
PCM Playback Data (Slots 3-11)
PD[19:0]
Playback Data. The PD[19:0] bits contain the 20-bit PCM (2
s complement) playback data for
the left and right DACs, serial data ports, and/or the S/PDIF transmitter. Table 10 on page 35
lists a cross reference for each function and its respective slot. The mapping of a given slot
to the DAC, serial data port, or S/PDIF transmitter is determined by the state of the ID[1:0]
bits in the
Extended Audio ID Register (Index 28h)
and by the SM[1:0] and AMAP bits in the
AC Mode Control Register (Index 5Eh)
.
3.1.5
GPIO Pin Control (Slot12)
GPIO[1:0]
GPIO Pin Control. The GPIO[1:0] bits control the CS4201 GPIO pins configured as outputs.
Write accesses using GPIO pin control bits configured at outputs will be reflected on the GPIO
pin output on the next AC-link frame. Write accesses using GPIO pin control bits configured
as inputs will have no effect and are ignored. If the GPOC bit in the
Misc. Crystal Control Reg-
ister (Index 60h)
is
set
, the bits in output Slot 12 are ignored and GPIO pins configured as
outputs are controlled through the
GPIO Pin Status Register (Index 54h)
.
