2.2.2 P10 to P17 (port 1)
interface data I/O, clock I/O, and timer I/O.
(1) Port mode
(2) Control mode
P10 to P17 function as an 8-bit I/O port. These pins also function as pins for external interrupt request input, serial
The following operation modes can be specified in 1-bit units.
P10 to P17 function as an 8-bit I/O port. P10 to P17 can be set to input or output port in 1-bit units using port
mode register 1 (PM1). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 1
(PU1).
P10 to P17 function as external interrupt request input, serial interface data I/O, clock I/O, and timer I/O.
