Host Request
When the HI08 is programmed to interface with a single host request host
bus and the HI function is selected, this signal is the Host Request
(HREQ) output. The polarity of the host request is programmable, but is
configured as active-low (HREQ) following reset. The host request can be
programmed as a driven or open-drain output.
Transmit Host Request
When the HI08 is programmed to interface with a double host request
host bus and the HI function is selected, this signal is the Transmit Host
Request (HTRQ) output. The polarity of the host request is
programmable, but is configured as active-low (HTRQ) following reset.
The host request may be programmed as a driven or open-drain output.
Port B 14
When the HI08 is configured as GPIO through the HPCR, this signal is
individually programmed through the HDDR. This input is 5 V tolerant.
Host Acknowledge
When the HI08 is programmed to interface with a single host request host
bus and the HI function is selected, this signal is the Host Acknowledge
(HACK) Schmitt-trigger input. The polarity of the host acknowledge is
programmable, but is configured as active-low (HACK) after reset.
Receive Host Request
When the HI08 is programmed to interface with a double host request
host bus and the HI function is selected, this signal is the Receive Host
Request (HRRQ) output. The polarity of the host request is
programmable, but is configured as active-low (HRRQ) after reset. The
host request may 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 through the HDDR. This input is 5 V tolerant.
