Serial interface
transmission data
output pin
Transmission data output pins for serial
interface 0, 1, and 2.
Select output by the P1DIR and P2DIR regis-
ters and serial pin function by the P1MD and
P2MD registers.
These can be used as normal I/O pins when
serial interfaces are not used.

Timer I/O pin Event counter input and timer pulse output
pins for 8-bit timer 1 to 5, 7 and 17.
At event count input, input mode dan be
selected by the P1, 3 and 5DIR registers. At
input mode, pull-up resistor can be selected
by the P1, 3 and 5PLU registers.
At timer pulse output, selected timer output
pins by the P1,3 and 5MD registers and set
output mode by the P1,3 and 5DIR 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, timer output, and PWM
output pins for 16-bit timer 8 to 11.
At event counte input, input mode can be
selected by the P3, 4, and 7DIR registers. At
input mode, pull-up resistor can be selected
by the P3, 4, and 7PLU register.
At timer output and PWM output, select timer
output pins by the P3, 4, and 7MD registers,
and set 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.

PWM output pin Motor control PWM signal output pins for 16-
bit timer 11. These output PWM signals for
16-bit timer 11 to 2 pins simultaneously.
At PWM output, select timer output pin by
the P7MD register and set to output mode by
the P7DIR register.
These can be used as normal I/O pins when
these are not used as timer I/O pins.
