Input/Output
Host Read/Write (HRWB)—When the HI08 is programmed to
interface to a single-data-strobe host bus and the HI function is
selected, this signal is the Read/Write input.
These pins are disconnected internally.
Host Read Data (HRD)—This signal is the Read Data input when
the HI08 is programmed to interface to a double-data-strobe host
bus and the HI function is selected.
Port B GPIO (11)—This pin is a General Purpose I/O (GPIO) pin
when not configured for host port usage.

Input/Output
Host Data Strobe (HDS)—When the HI08 is programmed to
interface to a single-data-strobe host bus and the HI function is
selected, this input enables a data transfer on the HI when HCS is
asserted.
These pins are disconnected internally.
Host Write Enable (HWR)—This signal is the Write Data input
when the HI08 is programmed to interface to a double-data-strobe
host bus and the HI function is selected.
Port B GPIO (12)—This pin is a General Purpose I/O (GPIO) pin
when not configured for host port usage.

Input/Output
Host Chip Select (HCS)—This input is the chip select input for the
Host Interface.
These pins are disconnected internally.
Port B GPIO (13)—This pin is a General Purpose I/O (GPIO) pin
when not configured for host port usage.

Output
Input/Output
Host Request (HREQ)—When the HI08 is programmed for
HRMS=0 functionality (typically used on a single-data-strobe bus),
this open drain output is used by the HI to request service from the
host processor. The HREQ may be connected to an interrupt
request pin of a host processor, a transfer request of a DMA
controller, or a control input of external circuitry.
These pins are disconnected internally.
Transmit Host Request (HTRQ)—This signal is the Transmit 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 (14)—This pin is a General Purpose I/O (GPIO) pin
when not configured for host port usage.
