Terminal Count.
The VT82C586A asserts TC to DMA slaves as a terminal count
indicator.
Interrupt Request.
The IRQ signals provide both system board components and
ISA Bus I/O devices with a mechanism for asynchronously interrupting the CPU.
DMA Request.
The DREQ lines are used to request DMA services from the
VT82C586A’s DMA controller.
Multifunction Pins
Pin 135 (ROMCS#/KBCS#) strapped 1 at power up:
Normal Operation:
Acknowledge.
The DACK output lines indicate a request for
DMA service has been granted.
Power-up:
Strap Inputs.
Strapped inputs stored in configuration register 96h.
Pin 135 (ROMCS#/KBCS#) strapped 0 at power up:
Pin 60:
DACEN.
To enable external 137 for decoding DACKs from XD0-2.
Other pins:
External SMI or General Purpose Inputs.
Multifunction Pin
Normal Operation:
Speaker Drive.
The SPKR signal is the output of counter 2.
Power-up Strapping:
0/1 = Fixed/flexible IDE I/O base
Enhanced IDE Interface
Disk I/O Read A.
Primary IDE channel drive read strobe.
Disk I/O Write A.
Primary IDE channel drive write strobe.
Disk I/O Read B.
Secondary IDE channel drive read strobe.
Disk I/O Write B.
Secondary IDE channel drive write strobe.
I/O Channel Ready A.
IDE drive ready indicator.
I/O Channel Ready B.
IDE drive ready indicator from the second channel (required
for UltraDMA/33 IDE interface).
System Address Transceiver Output Enable.
This signal controls the output
enables of the 245 transceivers that interface the DD[15:0] signals to SA[15:0]. The
transceiver direction controls are driven by MASTER# with DD[15-0] connected to
the “A” side of the transceivers and SA[15-0] connected to the “B” side.
Disk DMA Request A.
Primary IDE channel DMA request.
Disk DMA Request B.
Secondary IDE channel DMA request.
Disk DMA Acknowledge A.
Primary IDE channel DMA acknowledge.
Disk DMA Acknowledge B.
Secondary IDE channel DMA acknowledge. This pin
is used as a power-up strap option: 0/1 = Fixed/relocatable IDE I/O address
