Timer I/O pins
Event counter clock input pins, timer output and PWM
signal output pins for 8-bit timers 0 to 3.
To use these pins as event clock inputs, configure them
as inputs by the P1DIR register. When the pins are
used as inputs, pull-up and pull-down resistors can be
specified by the P1PLUD register.
For timer output, PWM signal output, select the special
functi on pi n b y the port 1 outp ut mode regi ster
(P1OMD) and set to the output mode by the P1DIR
register.
When not used for timer I/O, these can be used as
normal I/O pins.

Remote control
transmission signal
output pin
Output pin for remote control transmission signal with
a carrier signal.
For remote control carrier output, select the special
functi on pi n b y the port 1 outp ut mode regi ster
(P1OMD) and set to the output mode by the P1DIR
register. Also, set to the remote control carrier output
by the remote control carrier output control register
(RMCTR).
This can be used as a normal I/O pin when remote
control is not used.

Output
P06
Buzzer output
Piezoelectric buzzer driver pin. The driving frequency
can be selected by the DLYCTR register.
Select output mode by the P0DIR register and select
P06 buzzer output by the DLYCTR register.
When not used for buzzer output, this pin can be used
as a normal I/O pin.

Timer I/O pin
Event counter clock input pin, timer output and PWM
signal output pin for 16-bit timer 7, 8.
To use this pin as event clock input, configure this as
and pull-down resi stors can be selected by the
P1PLUD register.
For timer output, PWM signal output, select the special
functi on pi n b y the port 1 outp ut mode regi ster
(P1OMD), and set to the output mode by the P1DIR
register.
When not used for timer I/O, this can be used as normal
I/O pin.

Synchronous output
pins
8-bit synchronous output pins.
Synchronous output for each bit can be selected
individually by the port 4 synchronous output control
register (P4SYO). Set to the output mode by the P4DIR
register.
When not used for synchronous output, these pins can
be used as a normal I/O pins.
