I/O
ISA Bus PC Data. PC_D15 to PC_D8 in conjunction with an active HI
SBHE
connects the AD1812 to the high byte data on the bus, while PC_D7
to PC_D0 connects to the low byte data on the bus.
Interrupt Request. IRQ (3, 4, 5, 7, 9, 10, 11, 12). Active HI signals indicating a
pending interrupt.
DMA Request. DRQ (0, 1, 3, 5, 6, 7). Active HI signals indicating a request for
DMA bus operation. DRQ0, DRQ1 and DRQ3 request 8-bit DMA operations
while DRQ5, DRQ6 and DRQ7 request 16-bit operations.
ISA Bus PC Address. Connects the AD1812 to the ISA bus address lines.
Address Enable. Active HI signal indicates DMA transfer. Active LO signal
indicates PIO transfer.
DMA Acknowledge.
DACK
(0, 1, 3, 5, 6, 7). Active LO signal indicating that a
DMA operation can begin.
I/O Read indicates a read operation.
I/O Write indicates a write operation.
System Byte High Enable. Active LO signal that indicates a byte is being trans-
ferred on the upper byte of the 16-bit bus.
IO Channel 16. Active LO signal indicating that one of the logical devices inside
the AD1812 is decoded as a 16-bit device.
Reset. Active HI.
Inverted Reset. Active LO.
