4.2.2 Port 1
using port mode register 1 (PM1). When the P10 to P17 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 1 (PU1).

Port 1 is an 8-bit I/O port with an output latch. Port 1 can be set to the input mode or output mode in 1-bit units
This port can also be used for external interrupt request input, serial interface data I/O, clock I/O, timer I/O, and
RESET input sets port 1 to input mode.
Figures 4-6 to 4-10 show block diagrams of port 1.
Caution When P10/SCK10/TxD0, P11/SI10/RxD0, and P12/SO10 are used as general-purpose ports, set
