FUNCTION
Interrupt Terminals
IRQ15/
RI_OUT 163
I/O
Interrupt Request 15. This terminal indicates an interrupt request
from one of the PC Cards. RI_OUT allows the RI input from the 1 6-
bit PC Card, CSTSCHG from CardBus Cards or PC Card removal
events to be output to the system. This signal is configured in the
Card Control Register of the TI Extension Registers.
PC Card Power Switch Terminals
LATCH 150
O
Power Switch Latch is asserted by the PCI1131 to indicate to the PC
Card power switch that the data on the DATA line is valid.
CLOCK 151
O
Power Switch Clock. Information on the DATA line is sampled at the
rising edge of CLOCK. The frequency of the clock is derived from
dividing the PCICLK by 36. The maximum frequency of this signal is
2 MHz.
DATA
152
O
Power Switch Data is used by the PCI1131 to serially communicate
socket power control information.
Speaker Control Terminal
SPKROUT/
SUSPEND 149
I/O
Speaker. SPKROUT carries the digital audio signal from the PC
Card.
SUSPEND, when enabled, this signal places the PCI1131 in
PCI1131 Suspend Mode (Section 6.0) . This pin is configured in the
Card Control Register (Section 7.29) of the TI Extension Registers.
