Parallel Host Interface (HDI08)
2.10
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.

Table 2-9 Host Interface
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.
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.
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 3.3V 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 3.3V tolerant.
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.
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.
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 3.3V tolerant.
