2.2 Description of Pin Functions
2.2.1 P00 to P06 (port 0)
and chip select input.
(1) Port mode
(2) Control mode
P00 to P06 function as a 7-bit I/O port. These pins also function as timer I/O, serial interface data I/O, clock I/O,
The following operation modes can be specified in 1-bit units.
P00 to P06 function as a 7-bit I/O port. P00 to P06 can be set to input or output 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).
P00 to P06 function as timer I/O, serial interface data I/O, clock I/O, and chip select input.
(a) TI000, TI001
(b) TI010, TI011
(c) TO00, TO01
(d) SI11
(e) SO11
(f) SCK11
(g) SSI11
These are the pins for inputting an external count clock to 16-bit timer/event counters 00 and 01 and are also
for inputting a capture trigger signal to the capture registers (CR000, CR010 or CR001, CR011) of 16-bit
timer/event counters 00 and 01.
These are the pins for inputting a capture trigger signal to the capture register (CR000 or CR001) of 16-bit
timer/event counters 00 and 01.
These are timer output pins.
This is a serial interface serial data input pin.
This is a serial interface serial data output pin.
This is the serial interface serial clock I/O pin.
This is the serial interface chip select input pin.
Note TI001, TI011, TO01, SI11, SO11, SCK11, and SSI11 are available only in the
