Figure 120. Center-aligned PWM waveforms (compare 0 register = 8)
Edge-aligned mode (CMS bit = 0)
In this operating mode, the PWM counter counts up to the value loaded in the 12-bit
compare register. Then the PWM counter is cleared and it restarts counting up.
The PWM signals are set to ‘0’ when the PWM counter reaches, in up-counting, the
corresponding 13-bit Compare register value and they are set to ‘1’ when the PWM counter
is cleared.
If the 13-bit compare register value is greater than the extended compare 0 register (the 13
bit is set to ‘0’), the corresponding PWM output signal is held at ‘1’.
If the 13-bit compare register value = 0, the corresponding PWM output signal is held at ‘0’.
