Signal Description

Host Address Input 1ÑWhen the HI08 is

programmed to interface a nonmultiplexed host bus

and the HI function is selected, this signal is line 1 of

the host address (HA1) input bus.

HA8

Input

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.

PB9

Input or

Output

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.

HA2

Input

Input

Note: This signal has a weak keeper to maintain the last state

even if all drivers are tri-stated.

Host Address Input 2ÑWhen the HI08 is

programmed to interface a nonmultiplexed host bus

and the HI function is selected, this signal is line 2 of

the host address (HA2) input bus.

HA9

Input

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.

PB10

Input or

Output

Port B 10ÑWhen 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.
