16-bit Timer
IX - 66 1-Shot Output
9.10 1-Shot Output
9.10.1 1-Shot Output Operation
1-shot output is to count only one time at a certain period of time.
■ Setting One Shot Output
1-shot operation is set by setting the TM0NE flag of the timer mode register (TMnMD) to “1”. 1-shot operation
stops the timer by matching the binary counter and the timer compare/capture A register
■ Count Timing of One Shot Output (TMCLE flag= 0)
The binary counter stops at the next count clock after the value of the binary counter matches the value of the
compare/capture register, and the TMXF flag is set to “0”. The setting value of the binary counter is “setting + 1”
of the compare/capture register.

■ Count Timing of One Shot Output (TMCLE flag= 1)
The binary counter stops operating at the next count clock after the binary and the compare/capture register
match, and the TMXF flag is set to “0”. The binary counter is cleared to 0x0000. Set the TMCNE flag to “1”
again after setting “0” to restart.
