[Precautions when operating in one-shot pulse mode]
1. If the count start bit is cleared to “0” during counting, the counter stops counting and the reload register’s

selecting an external trigger, there will be a delay equivalent to one cycle of count source at maximum
from when a trigger is input to the TAi
to “1.”
Therefore, when using the timer Ai interrupt (interrupt request bit), be sure to clear the timer Ai interrupt
request bit to “0” after above setting.
