Timer 2 count stop timing (R2L = “0216”, R2H = “0216”, W23 = “1”)
Notes 1: If the timer count stop timing and the timer underflow timing overlap while the CNTR pin output
is valid (W23=“1”), a hazard may occur in the PWM signal waveform.
2: When timer count is stopped during “H” interval of the PWM signal, timer is stopped after
the end of the “H” output interval.
