Transmission data output pins for serial
interface 0, 1, and 2.
Select output mode by the P1DIR and P2DIR
registers and serial pin function by the P1MD
and P2MD registers.
These can be used as normal I/O pins when
the serial interface is not used.

Timer I/O pin
Event counter input and timer pulse output
pin for 8-bit timer 0 to 7, and 14 to 17.
To use this pin as event counter input, select
input mode by the P1, 3, 5, and 8DIR regis-
ters. In input mode, pull-up resistor can be
selected by the P1, 3, 5, and 8PLU registers.
To use this pin as timer pulse output, select
timer output pin by the P1,3,5, and 8MD
registers and set to output mode by the
P1,3,5, and 8DIR registers.
These can be used as normal I/O pins when
these are not used as timer I/O pins.

Timer I/O pin
Event counter input, toggle output, and PWM
output pin for 16-bit timer 8 to 11.
To use this pin as event counter input, select
input mode by the P3, 4, and 7DIR registers.
In input mode, pull-up resistor can be
selected by the P3, 4, and 7PLU register.
To use this as timer output and PWM output,
select timer output pin by the P3, 4, and 7MD
registers, and set to output mode by the P3,
4, and 7DIR register.
These can be used as normal I/O pins when
these are not used as timer I/O pins.
