CHAPTER 2 PIN FUNCTIONS
Preliminary User’s Manual U17734EJ1V0UD

2.2 Description of Pin Functions
2.2.1 P00, P01 (port 0)
P00 and P01 function as a 2-bit I/O port. These pins also function as timer I/O.
The following operation modes can be specified in 1-bit units.
(1) Port mode
P00 and P01 function as a 2-bit I/O port. P00 and P01 can be set to input or output port in 1-bit units using port
mode register 0 (PM0). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 0
(PU0).
(2) Control mode
P00 and P01 function as timer I/O.
(a) TI000
This is the pin for inputting an external count clock to 16-bit timer/event counter 00 and is also for inputting a
capture trigger signal to the capture registers (CR000, CR010) of 16-bit timer/event counter 00.
(b) TI010
This is the pin for inputting a capture trigger signal to the capture register (CR000) of 16-bit timer/event
counter 00.
(c) TO00
This is timer output pin.
2.2.2 P10 to P17 (port 1)
P10 to P17 function as an 8-bit I/O port. These pins also function as pins for external interrupt request input, serial
interface data I/O, clock I/O, and timer I/O.
The following operation modes can be specified in 1-bit units.
(1) Port mode
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).
(2) Control mode
P10 to P17 function as external interrupt request input, serial interface data I/O, clock I/O, and timer I/O.
(a) SI10
This is a serial interface serial data input pin.
(b) SO10
This is a serial interface serial data output pin.
(c) SCK10
This is a serial interface serial clock I/O pin.
