Host Read/Write
ÑWhen HI08 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.
Host Read Data
ÑWhen HI08 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.
Port B 11
ÑWhen the HI08 is configured as
GPIO through the HPCR, this signal is
individually programmed as an input or
output through the HDDR.

Host Data StrobeÑ
When HI08 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.
Host Write Data
ÑWhen HI08 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.
Port B 12
ÑWhen the HI08 is configured as
GPIO through the HPCR, this signal is
individually programmed as an input or
output through the HDDR.
