Function
A Main clock crystal oscillator pins (max. 4.2 MHz)
B Subclock crystal oscillator pins (32.768 kHz)
C
Operation mode selecting pins
Connect directly to VSS.
Reset I/O pin
This pin is of N-ch open-drain output type with pull-up re-
D sistor, and a hysteresis input type. The internal circuit is
initialized by the input of “L”. “L” is output from this pin by
an internal reset source as a option.
General-purpose I/O ports
I
On the MB89130A series, these ports also serve as an ex-
ternal interrupt input.
External interrupt inputs are of hysteresis input type.
E General-purpose I/O ports
G General-purpose output ports
General-purpose I/O port
F Also serves as the clock I/O for the 8-bit serial I/O. This
port is of hysteresis input type.
General-purpose I/O port
F Also serves as a 8-bit serial I/O data output. This port is of
hysteresis input type.
General-purpose I/O port
F Also serves as a 8-bit serial I/O data input. This port is of
hysteresis input type.
General-purpose I/O port
F
Also serves as the external clock input for the 8-bit
timer/counter. This port is of hysteresis input type. The
system clock output is provided as an option.
General-purpose I/O port
F
Also serve as the overflow output for the 8-bit timer/
counter and an external interrupt input. This port is of hys-
teresis input type.
