9.2 Block description of pulse output port 0
(2) Pulse output mode select bit (bit 3)
This bit is used to select the operation mode of pulse output port 0: pulse mode 0 or pulse mode 1.
(3) Pulse width modulation timer select bits (bits 5 and 4)
These bits are used to select the type of the pulse width modulation of pulse output port 0. Table 9.2.2
lists the functions of the pulse width modulation timer select bits.
(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: 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).
Table 9.2.2 Functions of pulse width modulation timer select bits
Note 1: The pulse width modulation cannot be applied to pins RTP10 to RTP13.
2: The pulse width modulation cannot be applied to pins RTP12 and RTP13.
