6.2.4 Port 3
mode register 3 (PM3). When the P30 and P31 pins are used as an input port, use of an on-chip pull-up resistor can be
specified in 1-bit units by pull-up resistor option register 3 (PU3).

P30/RTC1HZ/INTP3
P31/TI03/TO03/INTP4
Port 3 is an I/O port with an output latch. Port 3 can be set to the input mode or output mode in 1-bit units using port
This port can also be used for external interrupt request input, timer I/O, and real-time counter correction clock output.
Reset signal generation sets port 3 to input mode.
Figure 6-14 shows block a diagram of port 3.
Cautions 1. To use P31/TI03/TO03/INTP4 as a general-purpose port, set bit 3 (TO03) of timer output register 0
2. To use P30/RTC1HZ/INTP3 as a general-purpose port, set bit 5 (RCLOE1) of real-time counter
(TO0) and bit 3 (TOE03) of timer output enable register 0 (TOE0) to “0”, which is the same as their
default status setting.
control register 0 (RTCC0) to “0”, which is the same as its default status setting.
