Host Data—When the HDI08 is programmed to

interface a nonmultiplexed host bus and the HI

function is selected, these signals are lines 0–7

of the bidirectional, tri-state data bus.

Host Address—When HDI08 is programmed to

interface a multiplexed host bus and the HI

function is selected, these signals are lines 0–7

of the address/data bidirectional, multiplexed, tri-

state bus.

Port B 0–7—When the HDI08 is configured as

GPIO, these signals are individually

programmable as input, output, or internally

disconnected.

The default state after reset for these signals is

GPIO disconnected.

This input is 5 V tolerant.

Host Address Input 0—When the HDI08 is

programmed to interface a nonmultiplexed host

bus and the HI function is selected, this signal is

line 0 of the host address input bus.

Host Address Strobe—When HDI08 is

programmed to interface a multiplexed host bus

and the HI function is selected, this signal is the

host address strobe (HAS) Schmitt-trigger input.

The polarity of the address strobe is

programmable, but is configured active-low

(HAS) following reset.

Port B 8—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.
