The setting value of the binary counter is “setting + 1”of the compare/capture register.Figure:9.10.1 Count Timing of One Shot Output (TMCLE flag= 0)■ 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 registermatch, 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.Figure:9.10.2 Count Timing of One Shot Output (TMCLE flag= 1)TMnCNEflagTMnXFflag000300010000 0002 0003 0004CountclockCompare/captureregisterBinary counterTMnCNEflagTMnXFflag00030001 0002 0003 0000CountclockCompare/captureregisterBinary counter
