When a logic “0” is read on this
pin, the device needs servicing. It
remains asserted until the
pending interrupt is
acknowledged. This pin is an open
drain output for an external wired
“OR” logic implementation.
Motorola MPC860
microprocessor interface transfer
acknowledge. This pin requires an
external 1K pull-up resistor. This
pin is only used in the Motorola
MPC860 microprocessor
interface mode.
These eight bits are a bidirectional
data bus for transferring the read
and write data.
microprocessor interface mode,
the data bus is multiplexed with
address lines [7:0]. See
