39
X1
Crystal or other resonator connector pins for the main clock.
A The external clock can be connected to X0. When this is done, be
sure to leave X1 open.
40
41
MODA
C
Memory access mode setting pin.
Connect directly to VSS.
43
44
RST
Reset I/O pin.
This pin is an N-ch open-drain output type with a pull-up resistor,
D and a hysteresis input type. “L” is output from this pin by an
internal reset request (optional).
The internal circuit is initialized by the input of “L”.
44 to 51
45 to 52
P07/INT27 to
P00/INT20
General-purpose I/O ports.
E Also serve as an external interrupt 2 input (wake-up function).
External interrupt 2 input is hysteresis input.

P10/SEG24/
INT10 to
P12/SEG26/
INT12
P13/SEG27/
INT13
General-purpose I/O ports.
Also serve as input for external interrupt 1 input.
E/K The interrupt 1 input is a hysteresis type.
Also serve as LCD controller/driver segment output.
Switching is done by the mask option.
26 to 29
27 to 30
P14/SEG28 to
P17/SEG31
F/K
General-purpose I/O ports.
Also serve as LCD controller/driver segment output.
Switching is done by the mask option.
37
