CHAPTER 13 16-BIT PPG TIMER
■
Gate Trigger (PPG channel 0 only)
When gate trigger is used, PPG starts operation when rising edge of gate trigger is detected and stops when
falling is detected. In next rising edge, PPG restarts operation again.
Figure 13.6-5 Gate Trigger in PWM Mode when retriggering is enable
■
PPG Interrupts
There are four types of interrupts sharing one interrupt flag (PCNTL:IRQF) selected by interrupt type bits
(PCNTL:IRS1,IRS0).
•
Gate trigger (for PPG channel 0 only) or software trigger or retrigger
•
Counter borrow
•
Duty match occurs when PPG output rising in normal polarity or PPG output falling in inverted polarity
•
Counter borrow or duty match
