Host Chip Select—When HDI08 is programmed

to interface a nonmultiplexed host bus and the HI

function is selected, this signal is the host chip

select (HCS) input. The polarity of the chip select

is programmable, but is configured active-low

(HCS) after reset.

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.

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.

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.

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.

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.
