Tri-stated Host Parity Error—When the HI32 is programmed
to interface a PCI bus and the HI function is
selected, this is the Host Parity Error signal.
Host DMA Request—When HI32 is programmed
to interface a universal non-PCI bus and the HI
function is selected, this signal is Host DMA
Request output.
Port B—When the HI32 is configured as GPIO
through the DCTR, this signal is internally
disconnected.
This input is 5 V tolerant.
Input Host Bus Grant—When the HI32 is programmed
to interface a PCI bus and the HI function is
selected, this is the Host Bus Grant signal.
Host Address Enable—When HI32 is
programmed to interface a universal non-PCI bus
and the HI function is selected, this signal is Host
Address Enable input.
Port B—When the HI32 is configured as GPIO
through the DCTR, this signal is internally
disconnected.
This input is 5 V tolerant.
