Tri-stated
Host System Error
When the HI32 is programmed to interface with a PCI bus and the HI function
is selected, this is the Host System Error signal.
Host Interrupt Request
When HI32 is programmed to interface with a universal, non-PCI bus and the
HI function is selected, this is the Host Interrupt Request signal.
Port B
When the HI32 is configured as GPIO through the DCTR, this signal is
internally disconnected.
This input is 5 V tolerant.

Host Stop
When the HI32 is programmed to interface with a PCI bus and the HI function
is selected, this is the Host Stop signal.
Host Write/Host Read-Write
When HI32 is programmed to interface with a universal, non-PCI bus and the
HI function is selected, this is the Host Write/Host Read-Write Schmitt-trigger
signal.
Port B
When the HI32 is configured as GPIO through the DCTR, this signal is
internally disconnected.
This input is 5 V tolerant.

Host Initialization Device Select
When the HI32 is programmed to interface with a PCI bus and the HI function
is selected, this is the Host Initialization Device Select signal.
Host Read/Host Data Strobe
When HI32 is programmed to interface with a universal, non-PCI bus and the
HI function is selected, this is the Host Data Read/Host Data Strobe Schmitt-
trigger signal.
Port B
When the HI32 is configured as GPIO through the DCTR, this signal is
internally disconnected.
This input is 5 V tolerant.
HFRAME

Host Frame
When the HI32 is programmed to interface with a PCI bus and the HI function
is selected, this is the Host cycle Frame signal.
Non-PCI bus
When HI32 is programmed to interface with a universal, non-PCI bus and the
HI function is selected, this signal must be connected to a pull-up resistor or
directly to VCC.
Port B
When the HI32 is configured as GPIO through the DCTR, this signal is
internally disconnected.
This input is 5 V tolerant.
