CHAPTER 7 8-BIT PWM TIMER
Figure 7.7-2 Output Example of the PWM Waveform of 8-bit PWM Timer Functions
Notes:
• While PWM timer functions are enabled (CNTR: TPE = 1), do not change the count clock cycle
(CNTR: P1, P0).
• While PWM timer functions are enabled, the level immediately before the stop is held as the output
level of the PWM pin in the counter stop state (CNTR: TPE = 0).
