3.3.8 Notes on PWM output circuit
●“L” level output before starting PWM output
When at least one of two is set to “1” when both the PWM0 function enable bit and the PWM1 function
enable bit are “0”, “L” level is output from the corresponding PWM pin during the period shown below.
Then, PWM output is started from “H” level.
Count source selection bit = “0”, where n is the value set in the prescaler
sec.
Count source selection bit = “1”, where n is the value set in the prescaler
sec.
n + 1
2 f(XIN)
n + 1
f(XIN)
●Change of PWM output
When the PWM prescaler and the PWM register are changed during PWM output, the PWM waveforms
corresponding to updated data will be output from the next repetitive cycle. Figure 3.3.8 shows the
change of PWM output.
