Tri-stated Host AcknowledgeWhen the HI08 is programmed to
interface a single host request host bus and the HI function
is selected, this signal is the Host Acknowledge Schmitt-
trigger input (HACK). The polarity of the host acknowledge
is programmable.
Receive 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 Receive Host Request output
(HRRQ). The polarity of the host request is programmable.
The host request can be programmed as a driven or open-
drain output.
Port B 15
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.
