■ Notes on Using 8/16-bit PPG
● Note on operation
Depending on the timing between the activation of PPG and count clock, an error may occur in
the first cycle of the PPG output immediately after the activation. The error varies depending
on the count clock selected. The output, however, is performed properly in the succeeding
cycles.
● Note on interrupts
A PPG interrupt is generated when the interrupt enable bit (PIE1/PIE0) is set to "1" and the
interrupt request flag bit (PUF1/PUF0) in the 8/16-bit PPG timer n1/n0 control register (PCn1/
PCn0) is also set to "1". Always clear the interrupt request flag bit (PUF1/PUF0) to "0" in the
interrupt service routine.
