HA10
Input
GPIO
disconnected
Host Address 10—When HDI08 is programmed to interface a multiplexed
host bus and the HI function is selected, this signal is line 10 of the host
address (HA10) input bus.
PB13
Input, output, or
disconnected
GPIO
disconnected
Port B 13—When the HDI08 is configured as GPIO, this signal is
individually programmed as input, output, or internally disconnected.
The default state after reset for this signal is GPIO disconnected.
This input is 5 V tolerant.
HOREQ/
HOREQ
Output
GPIO
disconnected
Host Request—When HDI08 is programmed to interface a single host
request host bus and the HI function is selected, this signal is the host
request (HOREQ) output. The polarity of the host request is programmable,
but is configured as active-low (HOREQ) following reset. The host request
may be programmed as a driven or open-drain output.
HTRQ/
HTRQ
Output
GPIO
disconnected
Transmit Host Request—When HDI08 is programmed to interface 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.
PB14
Input, output, or
disconnected
GPIO
disconnected
Port B 14—When the HDI08 is configured as GPIO, this signal is
individually programmed as input, output, or internally disconnected.
The default state after reset for this signal is GPIO disconnected.
This input is 5 V tolerant.
HACK/
HACK
Input
GPIO
disconnected
Host Acknowledge—When HDI08 is programmed to interface 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.
HRRQ/
HRRQ
Output
GPIO
disconnected
Receive Host Request—When HDI08 is programmed to interface 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.
PB15
Input, output, or
disconnected
GPIO
disconnected
Port B 15—When the HDI08 is configured as GPIO, this signal is
individually programmed as input, output, or internally disconnected.
The default state after reset for this signal is GPIO disconnected.
This input is 5 V tolerant.
