CHAPTER 7 8-BIT PWM TIMER

7.8States in Each Mode During Operation

This section describes the operations for a move to the sleep mode, a move to the stop mode, and the occurrence of a suspend request during the operation of an 8-bit PWM timer.

■Operations in the Standby Mode and at a Suspension

When the mode is moved to sleep and stop modes, and when a suspend request occurs, the counter value status in which interval timer functions are enabled is shown in the Figure 7.8-1 , and the counter value status in which PWM timer functions are enabled is shown in the Figure 7.8-2 .

When switched to the stop mode, the counter holds a value and stops. When the stop mode is released by an external interrupt, the counter starts operation from the held value. Therefore, the first interval and the first cycle of the PWM waveform are not the values that are set. After the release of the stop mode, initialize the 8-bit PWM timer.
