Input
Connection for the external system clock
RC or ceramic oscillator element
When a single pin is used for external clock
input, the PI0/OSC2 pin is used as the PI0
I/O port.
When a 2-pin RC oscillator or a 2-pin ceramic
oscillator is used, the PI0/OSC2 pin is used as
the OSC2 oscillator pin.
1. Single-pin external clock input
2. 2-pin RC oscillator
3. 2-pin ceramic oscillator
4. Divider circuit option
No divider
Divide-by-three circuit
Divide-by-four circuit

PA0 to PA3
I/O
I/O port A0 to 3
Input in 4-bit units (IP instruction)
Output in 4-bit units (OP instruction)
Test in single-bit units (BP and BNP instructions)
Set/reset in single-bit units (SPB and RPB
instructions)
PA3 (Any one of PA0 to 3 can be selected) is
used for standby mode control.
Applications must assure that key bounce or
similar noise does not occur on PA3
(or PA0 to 3)
during a HALT instruction execution cycle.

2. Built-in pull-up resistor
Options 1 and 2 may be specified

The output level at reset can be specified to be 4. Low-level output at reset
either high or low.
Note: This port does not have the standby
mode control function.
