RIOLED is RI Out.
This bit determines the function of the RIOLED. When configured for ring indicate, RIOLED is
used to resume the 386SL when a high to low change is detected on the STSCHG#.
0: Tri-state RIOLED if RIOLED is not used as LED output
1: RIOLED is connected to Ring Indicate on the processor.
R/W. 0
Tri-state SD7 bit.
This bit enables floppy change bit compatibility.
0: Normal operation.
1: For I/O PC Card at address 03F7h and 0377h, do not drive SD7 bit.
Drive LED Enable.
This bit determines when SPKR# is used to drive an LED on RIOLED for disk access.
0: Tri-state RIOLED if RIOLED is not used as RI out.
1: RIOLED becomes an open drain output suitable for driving an LED.
