Parallel Host Interface (HDI08)
The HDI08 provides a fast, 8-bit, parallel data port that may be connected directly to the host bus. The
HDI08 supports a variety of standard buses and can be directly connected to a number of industry standard
microcomputers, microprocessors, DSPs, and DMA hardware.

Signal Name
Type
State during
Reset
Signal Description
H0–H7
Input/
output
GPIO
disconnected
Host Data—When 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.
HAD0–HAD7
Input/
output
GPIO
disconnected
Host Address/Data—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.
PB0–PB7
Input, output, or
disconnected
GPIO
disconnected
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.
These inputs are 5 V tolerant.
HA0
Input
GPIO
disconnected
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.
HAS/HAS
Input
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.
PB8
Input, output, or
disconnected
GPIO
disconnected
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.
HA1
Input
GPIO
disconnected
Host Address Input 1—When the HDI08 is programmed to interface a
nonmultiplexed host bus and the HI function is selected, this signal is line 1
of the host address (HA1) input bus.
HA8
Input
GPIO
disconnected
Host Address 8—When HDI08 is programmed to interface a multiplexed
host bus and the HI function is selected, this signal is line 8 of the host
address (HA8) input bus.
PB9
Input, output, or
disconnected
GPIO
disconnected
Port B 9—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.
