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.
