CHAPTER 16 8/16-BIT PPG
16.7
8/16-bit PPG Interrupts
For the 8/16-bit PPG, an interrupt becomes active when the reload value counts out and
a borrow occurs.
■ 8/16-bit PPG Interrupts
In 8-bit PPG 2ch mode or 8-bit prescaler + 8-bit PPG mode, an interrupt is requested by a borrow in each
counter. In 16-bit PPG mode, PUF0 and PUF1 are simultaneously set by a borrow in the 16-bit counter.
Therefore, enable only PIE0 or PIE1 to unify the interrupt causes. In addition, simultaneously clear the
interrupt flags for PUF0 and PUF1.
