Input/Output
Host Acknowledge (HACK)—When the HI08 is programmed for
HRMS=0 functionality (typically used on a single-data-strobe bus), this
input has two functions: (1) provide a Host Acknowledge signal for
DMA transfers or (2) to control handshaking and provide a Host
Interrupt Acknowledge compatible with the MC68000 family
processors.
These pins are disconnected internally during reset.
Receive Host Request (HRRQ)—This signal is the Receive Host
Request output when the HI08 is programmed for HRMS=1
functionality and is typically used on a double-data-strobe bus.
Port B GPIO (15)—This pin is a General Purpose I/O (GPIO) pin when
not configured for host port usage.

Timer Input/Outputs (TIO0)—This pin can be independently

can individually be programmed as an input or output pin.

Input
External Interrupt Request A and B—The IRQA and IRQB inputs
are asynchronous external interrupt requests that indicate that an
external device is requesting service. A Schmitt trigger input is used
for noise immunity. They can be programmed to be level-sensitive or
negative-edge-triggered. If level-sensitive triggering is selected, an
external pull-up resistor is required for Wired-OR operation.

Mode Select (MODE A)—During the bootstrap process MODE A
selects one of the eight bootstrap modes.
Port H GPIO (0)—This pin is a General Purpose I/O (GPIO) pin after
the bootstrap process has completed.
