In programmable wait one-shot generation mode, a one-shot pulse is output from the TRBO pin by a program or an
external trigger input (input to the INT0 pin) (refer to Table 18.5 Programmable Wait One-Shot Generation Mode
Specifications). When a trigger is generated from that point, the timer outputs a pulse only once for a given length
of time equal to the setting value in the TRBSC register after waiting for a given length of time equal to the setting
value in the TRBPR register.
Figure 18.5 shows an Operating Example of Programmable Wait One-Shot Generation Mode.
