Section 8 14-Bit PWM Timer (PWMX)
8.5
A PWM waveform like the one shown in figure 8.2 is output from the PWX pin. The value in
DADR corresponds to the total width (T
(256 pulses when CFS = 0, 64 pulses when CFS = 1). When OS = 0, this waveform is directly
output. When OS = 1, the output waveform is inverted, and the DADR value corresponds to the
total width (T
output available.
