FUNCTION
Parallel Interrupt Requested Input 5.
Parallel Interrupt Requested Input 6.
Parallel Interrupt Requested Input 7.
Parallel Interrupt Requested Input 9.
Parallel Interrupt Requested Input 10.
Parallel Interrupt Requested Input 11.
Parallel Interrupt Requested Input 12.
Parallel Interrupt Requested Input 14.
Parallel Interrupt Requested Input 15.
DMA Request 0. The DREQ signal indicates that either a
slave DMA device is requesting DMA services, or an ISA
bus master is requesting use of the ISA bus.
DMA Request 1.
DMA Request 2.
DMA Request 3.
DMA Request 5.
DMA Request 6.
DMA Request 7.
DMA Acknowledge 0. The DACK# signal indicates that
either a DMA channel or an ISA bus master has been
granted the ISA bus.
DMA Acknowledge 1.
DMA Acknowledge 2.
DMA Acknowledge 3.
DMA Acknowledge 5.
DMA Acknowledge 6.
During power-on reset, this is pulled-hi internally (Select
4Eh) and is defined as HEFRAS which provides the
power-on value for CR3 bit4. A 4.7k ohm is recommended
if intends to pull down. (Select 2Eh)
DMA Acknowledge 7.
Terminal Count. The W83628F asserts TC to DMA slaves
as a terminal count indicator.
