H / E
General-purpose CMOS input port for MB89F202.
General-puspose CMOS I/O port for MB89202/MB89V201.

RST
C
Reset I/O pin.
This pin serves as an N-channel open-drain reset output with pull-up
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.

G
General-purpose CMOS I/O ports.
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.
