Signal Description
Host Chip SelectÑWhen HI08 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.
HA10
Input
Host Address 10ÑWhen HI08 is programmed to
interface a multiplexed host bus and the HI function
is selected, this signal is line 10 of the host address
(HA10) input bus.
PB13
Input or
Output
Port B 13ÑWhen the HI08 is configured as GPIO
through the HPCR, this signal is individually
programmed as an input or output through the
HDDR.
Note: This signal has a weak keeper to maintain the last state
even if all drivers are tri-stated.
