ISA Bus System Address 23 to 17
ISA Bus System Address 16 to 0
Address Enable. High signal is input in DMA
mode.
Address Latch Enable. This signal latches LA23
pin to LA17 pin.
System Bus High Byte Enable
This active low signal indicates that an ISA-bus
refresh cycle is either requested or in progress.

I/O Channel Ready. This active High signal indi-
cates that the accessed device on the ISA-bus is
ready to terminate the bus cycle.
Interrupt Request Signal.
IRQ3, IRQ4, IRQ5, IRQ7, IRQ9, IRQ10, IRQ11,
IRQ12, IRQ14, IRQ15. Level mode interrupt or
Edge mode interrupt is programmable. IRQ12
can be used as a LED driver. IRQ9, IRQ10,
IRQ11, or IRQ15 may be used as system side
DACK#, system side DREQ, and system side TC
respectively in DMA mode.
