(1) Waveform output select bits (bits 2 to 0)
These bits are used to select whether a pin serves as a programmable I/O port pin or
a pulse output pin. Table 9.2.1 lists the functions of the waveform output select bits.

Port
Port: This serves as a programmable I/O port pin or timer I/O pin.
RTP: This serves as a pulse output pin regardless of the contents of the corresponding port direction register.
Note: This is selected by the pulse output mode select bit (bit 3 at address A616).
