Change of Peripheral Function Pins

I/O ports that also function as peripheral modules, such as the 8-bit PWM timer output, external
interrupts, and TPU I/O, and, can be changed. They are changed according to the setting of
PTCNT0 to PTCNT2. The pin name of the peripheral function is indicated by adding 'Ex' at the
head of the original pin name. In each peripheral function description, the original pin name is
used.
