14.2.4 Programmable Wait One-shot Generation Mode
Programmable wait one-shot generation mode is mode to output the one-shot pulse from the TRBO pin by a
program or an external trigger input (input to the INT0
pin) (see Table 14.10 Programmable Wait One-Shot
Generation Mode Specifications). When a trigger is generated from this point, the timer starts outputting
pulses 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 14.23 shows the TRBIOC Register in Programmable Wait One-Shot Generation Mode. Figure 14.24
shows the Operation Example of Programmable Wait One-Shot Generation Mode.
