RIENB
RW
Ring indicate enable. When this bit is 1, the RI_OUT output is enabled. This bit defaults to 0.
63
RSVD
RW
These bits are reserved. Do not change the value of these bits.
2
AUD2MUX
RW
CardBus audio-to-MFUNC. When this bit is set, the CAUDIO CardBus signal must be routed through an
MFUNC terminal.
0 = CAUDIO set to CAUDPWM on MFUNC terminal (default)
1 = CAUDIO is not routed.
1
SPKROUTEN
RW
When bit 1 is set, the SPKR terminal from the PC Card is enabled and is routed to tthe SPKROUT terminal.
The SPKROUT terminal drives data only when the SPKROUTEN bit of the function is set. This bit is
encoded as:
0 = SPKR to SPKROUT not enabled (default)
1 = SPKR to SPKROUT enabled
0
IFG
RW
Interrupt flag. This bit is the interrupt flag for 16-bit I/O PC Cards and for CardBus cards. This bit is set when
a functional interrupt is signaled from a PC Card interface. Write back a 1 to clear this bit.
0 = No PC Card functional interrupt detected (default)
1 = PC Card functional interrupt detected
One or more bits in this register are cleared only by the assertion of GRST.
