H/E

General-purpose CMOS input port for MB89F202.

General-puspose CMOS I/O port for MB89202/MB89V201.

RST

Reset I/O pin.

This pin serves as an N-channel open-drain reset output with pull-up

C

resistor (not available for MB89F202) and a reset input as well. The

reset is a hysteresis input.

It outputs the “L” signal in response to an internal reset request. Also,

it initializes the internal circuit upon input of the “L” signal.

P00/INT20/

28 to 31 30 to 33

AN4

to P03/

INT23/AN7

General-purpose CMOS I/O ports.

G

These pins also serve as an input (wake-up input) of external interrupt

2 or as an 10-bit A/D converter analog input. The input of external in-

terrupt 2 is a hysteresis input.
