Function
8 bit programmable I/O (large current) port
(try state)
I/O can be assigned by one bit. When
using as the serial interface input, the input
mode is selected.
When using as the serial interface output,
the output mode is selected with the output
latch “1” set.
8 bit programmable I/O (P14 ~ P10 are
large current) port (try state)
I/O can be assigned by one bit. When
using as the external interrupting input and/
or timer counter input, the input mode is
selected.
When using as the timer counter output
and/or divider output, the output mode is
selected with the output latch to “1” set.
3 bit I/O (large current output) port.
When using as the input port, external
interrupting input/STOP mode release input
and/or the oscillator connection, the output
mode is selected with the output latch to
“1” set.
3 bit programmable I/O port (sync open
drain).
I/O can be assigned by one bit.
When using as the serial bus interface, the
output mode is selected with the output
latch to “1” set.
8 bit programmable I/O port (try state)
I/O can be assigned by one bit. When
using as the analog input, the input mode
is selected.
4 bit programmable I/O port (try state)
I/O can be assigned by one bit. When
using as the analog input, the input mode
is selected.
8 bit high dielectric strength I/O port.
When using as the fluorescent display
driver, the output latch is cleared to “0”.
