14.4 Operations
(6) Interrupts
For this module, an interrupt becomes active when the reload value is counted out and a borrow occurs.
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, PUG0 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 causes for PUF0 and PUF1.
(7) Default values of hardware components
The hardware components of this block are initialized to the following values when reset:
<Registers>
<Pulse outputs>
<Interrupt requests>
Hardware components other than the above are not initialized.
