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 during reset.
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.

Host Chip Select (HCS)
—This input is the chip select input for the
Host Interface.
These pins are disconnected internally during reset.
Port B GPIO (13)

not configured for host port usage.

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 during reset.
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.
