Signal Description

GPIO Disconnected

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.
