P00/INT20 to

P07/INT27

F

General-purpose I/O ports

Also serve as an external interrupt 2 input (wake-up

function).

External interrupt 2 input (INT20 to INT27) is hysteresis

input while port input (P00 to P07) is CMOS input.

18 to 21

15 to 18

P10/INT10 to

P13/INT13

F

General-purpose I/O ports

Also serve as an external interrupt 1 input.

External interrupt 1 input (INT10 to INT13) is hysteresis

input while port input (P10 to P13) is CMOS input.

22 to 25

19 to 22

P14/INT28 to

P15/INT2B

F

General-purpose I/O ports

Also serve as an external interrupt 2 input (wake-up

function).

External interrupt 2 input (INT28 to INT2B) is hysteresis

input while port input (P14 to P17) is CMOS input.

P24/SI,

P25/SO,

P26/SCK

F

General-purpose I/O ports

The output type can be switched between N-ch open-

drain and CMOS. These ports also serve as an 8-bit se-

rial I/O.

The P26/SCK pin is a CMOS input type when it func-

tions as the port input (P26) while the pin is a hysteresis

input type when it functions as the serial clock input

(SCK).

32 to 47

P36/SEG31 to

P47/SEG26

H

General-purpose I/O ports

Also serve as an LCD controller/driver segment output.
