Port 1: This is a 4-bit group of I/O pins.

P11, P10

Input or output can be designated for

each bit by means of port control

P47 to

23 to 30 32 to 39 I/O

Port 4: This is an 8-bit high-voltage I/O

P40

port.

P77 to

55 to 48 64 to 57 I/O

Port 7: This is an 8-bit high-voltage I/O

P70

port.

P97 to

64 to 57 9 to 2

I/O

Port 9: This is an 8-bit I/O port. Input or

P90

output can be designated for each bit by

means of PCR9.

A/D converter

AN7 to

9 to 2

18 to 11 Input

Analog input channels 7 to 0: These

AN0

are analog data input channels to the

A/D converter.

VFD controller/

FD15 to

55 to 40 64 to 49 Output VFD digit output: These are digit output

driver

FD0

pins from the VFD controller/driver.

23 to 38 32 to 47 I/O

VFD segment output: These are

40 to 47 49 to 56

segment output pins from the VFD

controller/driver. When a key scan

interval is set during display operations,

these pins can be used by the CPU

during this interval as general-purpose

I/O ports.
