The lower four bits in PWMREG specify the position of pulses added to the 16 basic pulses. The
additional pulse adds a high period (when PHnS = 0) at the resolution width before the rising edge
of the basic pulse. Although there is no rising edge of the basic pulse when the upper four bits in
PWMREG is B'0000, the timing for adding pulses is the same. Table 8.7 shows the additional
pulse positions corresponding to the basic pulses, and figure 8.8 shows an example of additional
pulse timing.
