RTP1
by timer A3 by setting the pulse width modulation selection bit by
timer A3 (bit 5) of the waveform output mode register to “1”.
RTP0
by timer A1 by setting the pulse width modulation selection bit by
timer A1 (bit 4) of the waveform output mode register to “1”.
The contents of the pulse output data register 0 can be reversed and
output to pulse output ports RTP0
the polarity selection bit (bit 3) of the waveform output mode register.
When the polarity selection bit is “0”, the contents of the pulse output
data register 0 is output unchangeably, and when “1”, the contents of
the pulse output data register 0 is reversed and output. When pulse
width modulation is applied, likewise the polarity reverse to pulse
width modulation can be selected by the polarity selection bit.
