If the binarycounter reaches the compare register, and the binary counter is cleared to x'00', TMnIO output isinverted. The inversion of the timer output is changed at the rising edge of the count clock. This ishappened to form waveform inside to correct the output cycle.Table 6-5-1 Timer Pulse Output PinsFigure 6-5-1 Count Timing of Timer Pulse Output (Timers 0, 1, 4 and 5)
