SPKROUT and CAUDPWM Usage
SPKROUT carries the digital audio signal from the PC Card to the system. When a 16-bit PC Card is configured for
I/O mode, the BVD2 terminal becomes SPKR. This terminal is also used in CardBus binary audio applications, and
is referred to as CAUDIO. SPKR passes a TTL-level digital audio signal to the PCI1520. The CardBus CAUDIO signal
also can pass a single-amplitude binary waveform. The binary audio signals from the two PC Card sockets are XORed
in the PCI1520 to produce SPKROUT. This output is enabled by bit 1 (SPKROUTEN) in the card control register (PCI
offset 91h, see Section 4.32).
Older controllers support CAUDIO in binary or PWM mode but use the same terminal (SPKROUT). Some audio chips
may not support both modes on one terminal and may have a separate terminal for binary and PWM. The PCI1520
implementation includes a signal for PWM, CAUDPWM, which can be routed to an MFUNC terminal. Bit 2
(AUD2MUX), located in the card control register, is programmed on a per-socket function basis to route a CardBus
CAUDIO PWM terminal to CAUDPWM. If both CardBus functions enable CAUDIO PWM routing to CAUDPWM, then
socket 0 audio takes precedence. See Section 4.30,
Multifunction Routing Register
, for details on configuring the
MFUNC terminals.
