Figure 8.2 Example Of Additional Pulse Timing (When Upper 4 Bits Of Pwdr = B'1000); Table 8.5 Position Of Pulses Added To Basic Pulses - Renesas H8S/2111B Hardware Manual

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 8.5 shows the positions of
the additional pulses added to the basic pulses, and figure 8.2 shows an example of additional
pulse timing.
