In programmable waveform generation mode, the signal output from the TRBO pin is inverted each time the
counter underflows, while the values in registers TRBPR and TRBSC are counted alternately (refer to Table 18.3).
Counting starts by counting the setting value of the TRBPR register. The TRBOCR register is unused in this mode.
Figure 18.3 shows an Operating Example in Timer RB in Programmable Waveform Generation Mode.
