Host Address Input 1ÑWhen the HI08 is
programmed to interface a non-multiplexed
host bus and the HI function is selected, this
signal is line 1 of the host address (HA1)
input bus.
Host Address 8ÑWhen HI08 is programmed
to interface a multiplexed host bus and the
HI function is selected, this signal is line 8 of
the host address (HA8) input bus.
Port B 9ÑWhen the HI08 is configured as
GPIO through the HPCR, this signal is
individually programmed as an input or
output through the HDDR.
Host Address Input 2ÑWhen the HI08 is
programmed to interface a non-multiplexed
host bus and the HI function is selected, this
signal is line 2 of the host address (HA2)
input bus.
Host Address 9ÑWhen HI08 is programmed
to interface a multiplexed host bus and the
HI function is selected, this signal is line 9 of
the host address (HA9) input bus.
Port B 10ÑWhen the HI08 is configured as
GPIO through the HPCR, this signal is
