I
Interrupt acknowledge (active low). Indicating an interrupt
acknowledge cycle. XR68C92/192 will place the interrupt
vector on the data bus and will set -DTACK low if it has a
pending interrupt.

Bi-directional data bus. Eight bit, three state data bus to
transfer information to or from the CPU. D0 is the least
significant bit of the data bus and the first serial data bit to be
received or transmitted.

I
Read/Write strobe. When -CS is asserted, a high level on this
pin transfers the contents of the XR68C92/192 data bus to
the CPU, and a low level on this pin will transfer the contents
of the CPU data bus to the addressed register.
