10.5
A PWM waveform like the one shown in figure 10.2 is output from the PWX pin. DA13 to DA0
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 DA13 to DA0 in DADR value
corresponds to the total width (T
types of waveform output available.
Table 10.3 summarizes the relationships between the CKS and CFS bit settings and the resolution,
base cycle, and conversion cycle. The PWM output remains fixed unless DA13 to DA0 in DADR
contain at least a certain minimum value. The relationship between the OS bit and the output
waveform is shown in figures 10.3 and 10.4.
