1. Open-drain output
2. Built-in pull-up resistor
Options 1 and 2 may be specified
in bit units.

PF0/SI
PF1/SO
PF2/SCK
PF3/INT
I/O
I/O port F0 to 3
Functions and options identical to PE0 to 3.
(See note.)
PF0 to 3 have shared functions as the serial
interface pins and the INT input.
Either function can be selected under program
control.
SI ... Serial input port
SO ... Serial output port
SCK ... Serial clock input or output
INT ... Interrupt request input
Serial input/output is switched between 4-bit
and 8-bit units under program control.
Note: This port does not have a continuous
pulse output function.
The same as those for PE0 to 3.
The same as
that for PE0 to 3. that for
The serial port
is disabled and
INT is the
interrupt source.
The same as
PA0 to 3.

I/O port G0 to 3
Functions and options identical to PE0 to 3.

PI0/OSC2
I/O
I/O port IO
Functions and options identical to PG0 to 3.
However, consists of a single bit.
When a 2-pins oscillator is used, this pin
functions as the OSC2 pin, and the I/O port
function is not available.
The same as those for PG0 to 3.

PG0 to 3.
The same as
that for
PA0 to 3.
