The upper four bits of PWDR specify the duty cycle of the basic pulse as 0/16 to 15/16 with a
resolution of 1/16. Table 9.4 shows the duty cycles of the basic pulse.
Table 9.4
The lower four bits of PWDR specify the position of pulses added to the 16 basic pulses. An
additional pulse adds a high period (when OS = 0) with a width equal to the resolution before the
rising edge of a basic pulse. When the upper four bits of PWDR are 0000, there is no rising edge
of the basic pulse, but the timing for adding pulses is the same. Table 9.5 shows the positions of
