2.2 Description of Pin Functions

2.2.1 P00 and 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 are 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 the timer output pin of 16-bit timer/event counter 00.
