Host Read/Write
When the HI08 is programmed to interface with a single-data-strobe host
bus and the HI function is selected, this signal is the Host Read/Write
input.
Host Read Data
When the HI08 is programmed to interface with 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.
Port B 11
When the HI08 is configured as GPIO through the HPCR, this signal is
individually programmed through the HDDR. This input is 5 V tolerant.
Host Data Strobe
When the HI08 is programmed to interface with 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.
Host Write Data
When the HI08 is programmed to interface with 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.
Port B 12
When the HI08 is configured as GPIO through the HPCR, this signal is
individually programmed through the HDDR. This input is 5 V tolerant.
Host Chip Select
When the HI08 is programmed to interface with a non-multiplexed 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.
Host Address 10
When the HI08 is programmed to interface with a multiplexed host bus
and the HI function is selected, this signal is line 10 of the Host Address
bus.
Port B 13
When the HI08 is configured as GPIO through the HPCR, this signal is
individually programmed through the HDDR. This input is 5 V tolerant.
