HA2
Input
GPIO
disconnected
Host Address Input 2
—When the HDI08 is programmed to interface a
non-multiplexed host bus and the HI function is selected, this signal is line 2
of the host address (HA2) input bus.
HA9
Input
GPIO
disconnected
Host Address 9
—When HDI08 is programmed to interface a multiplexed
host bus and the HI function is selected, this signal is line 9 of the host
address (HA9) input bus.
PB10
Input, Output, or
Disconnected
GPIO
disconnected
Port B 10
—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.
HRW
Input
GPIO
disconnected
Host Read/Write
—When HDI08 is programmed to interface a
single-data-strobe host bus and the HI function is selected, this signal is the
Host Read/Write (HRW) input.
HRD/
HRD
Input
GPIO
disconnected
Host Read Data
—When HDI08 is programmed to interface a
double-data-strobe host bus and the HI function is selected, this signal is the
host read data strobe (HRD) Schmitt-trigger input. The polarity of the data
strobe is programmable, but is configured as active-low (HRD) after reset.
PB11
Input, Output, or
Disconnected
GPIO
disconnected
Port B 11
—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.
HDS/

Host Data Strobe—
When HDI08 is programmed to interface a
single-data-strobe host bus and the HI function is selected, this signal is the
host data strobe (HDS) Schmitt-trigger input. The polarity of the data strobe
is programmable, but is configured as active-low (HDS) following reset.
HWR/
HWR
Input
GPIO
disconnected
Host Write Data
—When HDI08 is programmed to interface a
double-data-strobe host bus and the HI function is selected, this signal is the
host write data strobe (HWR) Schmitt-trigger input. The polarity of the data
strobe is programmable, but is configured as active-low (HWR) following
reset.
PB12
Input, output, or
disconnected
GPIO
disconnected
Port B 12
—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.
HCS
Input
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.
