P2DDR is an 8-bit write-only register that specifies the input/output direction and PWM output for
each pin of port 2 on a bit-by-bit basis.
Port 2 pins are multiplexed with pins PW8 to PW15. The bit corresponding to a pin to be used for
PWM output should be set to 1.
For details on P2DDR, see section 8.3, Port 2.

P1DR is an 8-bit readable/writable register used to fix PWM output at 1 (when OS = 0) or 0 (when
OS = 1).
For details on P1DR, see section 8.2, Port 1.
