Signal Description
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.
GPIO
disconnected
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.
GPIO
disconnected
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.
