Function
Power supply
System clock oscillator
Connect an external ceramic oscillator
element to these pins
Leave OSC2 open if an external clock
is supplied.
I/O port A0 to A3
Input in 4-bit units using the IP
instruction
Output in 4-bit units using the OP
instruction
Port bits can be tested in bit units using
the BP and BNP instructions.
Port bits can be set or cleared in bit
units using the SPB and RPB
instructions.
PA3 is used for standby control.
Applications must be designed so that
no chattering (e.g. switch bounce)
occurs on the PA3 pin during a HALT
instruction execution cycle.
I/O port C0 to C3
The PC0 to PC3 pin functions are
identical to those of the PA0 to 3 pins.
*
High or low can be specified as the
output at reset as an option.
Note: These pins do not have a
standby control function.
I/O port D0 to D3
The PD0 to PD3 pin functions and
options are identical to those of the
PC0 to PC3 pins.
Options
—
(1) External clock
(2) Two-pin ceramic oscillator
(3) Divider circuit option
1. No divider circuit
2. Divide-by-three circuit
3. Divide-by-four circuit
(1) Output open drain
(2) Built-in pull-up resistor
Options (1) and (2) can be
specified in bit units.
(1) Output open drain
(2) Built-in pull-up resistor
(3) High-level output at reset
(4) Low-level output at reset
Options (1) and (2) can be
specified in bit units.
Option (3) and (4) are
specified in 4-bit units.
The same as PC0 to PC3.
