P40 to P47 constitute an 8-bit I/O port, port 4. In addition to I/O port pins, P41 to P44 also have functions to output
These pins can be set to the following operation modes in 1-bit units.
(1) Port mode
(2) Control mode
P120 to P123 constitute a 4-bit I/O port, port 12.
Each bit of this port can be set to the input or output mode by using port mode register 12 (PM12). An on-chip pull-
P121 and P122 also function as the X1 and X2, respectively. For settings of alternate function, refer to CHAPTER
Caution The P121/X1 and P122/X2 pins are pulled down during reset.
This is a 1-bit output-only port.
This pin inputs an active-low system reset signal. When the power is turned on, this is the reset function,
(d) TO00
P40 to P47 function as an 8-bit I/O port. Each bit of this port can be set to the input or output mode by using
port mode register 4 (PM4). In addition, an on-chip pull-up resistor can be connected to the port by using pull-
up resistor option register 4 (PU4).
P41 to 44 function to output a signal from an internal timer, input external interrupt request signals, and
input/output data of the serial interface.
(a) INTP1 and INTP3
(b) TOH1
(c) TxD6
(d) RxD6
This pin outputs a signal from 16-bit timer/event counter 00.
These are external interrupt request input pins for which the valid edge (rising edge, falling edge, or both
rising and falling edges) can be specified.
This is the output pin of 8-bit timer H1.
This pin outputs serial data from the asynchronous serial interface.
This pin inputs serial data to the asynchronous serial interface.
