Host Interface (HI08)
HCS/HCS
HA10
PB13
Input
Input or
Output
Tri-stated Host Chip SelectWhen the HI08 is programmed to
interface a non-multiplexed host bus and the HI function is
selected, this signal is the Host Chip Select input (HCS). The
polarity of the chip select is programmable.
Host Address 10
When the HI08 is programmed to
interface a multiplexed host bus and the HI function is
selected, this signal is line 10 of the input Host Address bus
(HA10).
Port B 13
When the HI08 is configured as GPIO through
the HPCR, this signal is individually programmed as an
input or output through the HDDR.
This pin is electrically disconnected internally during the
Stop processing state.

Output
Input or
Output
Tri-stated Host RequestWhen the HI08 is programmed to interface
a single host request host bus and the HI function is
selected, this signal is the Host Request output (HREQ). The
polarity of the host request is programmable. The host
request can be programmed as a driven or open-drain
output.
Transmit Host Request
When the HI08 is programmed to
interface a double host request host bus and the HI function
is selected, this signal is the Transmit Host Request output
(HTRQ). The polarity of the host request is programmable.
The host request can be programmed as a driven or open-
drain output.
Port B 14
When the HI08 is programmed to interface a
multiplexed host bus and the signal is configured as GPIO
through the HPCR, this signal is individually programmed
as an input or output through the HDDR.
This pin is electrically disconnected internally during the
Stop processing state.
