Section 10 8-Bit PWM Timer (PWM)
Rev. 3.00 Jan 25, 2006 page 271 of 872
REJ09B0286-0300
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 B'0000, there is no rising edge
of the basic pulse, but the timing for adding pulses is the same. Table 10.5 shows the positions of
the additional pulses added to the basic pulses, and figure 10.2 shows an example of additional
pulse timing.
