Section 9 8-Bit PWM Timers
The lower 4 bits of PWDR specify the position of pulses added to the 16 basic pulses, as shown in
table 9.5. An additional pulse consists of a high period (when OS = 0) with a width equal to the
resolution, added before the rising edge of a basic pulse. When the upper 4 bits of PWDR are
0000, there is no rising edge of the basic pulse, but the timing for adding pulses is the same.
