Interrupt

The 8/16-bit PPG outputs an interrupt request when a counter borrow is
detected.
■ Interrupt of 8/16-bit PPG
Table 18.5-1 shows the interrupt control bits and interrupt sources of the 8/16-bit PPG.
Table 18.5-1 Interrupt Control Bits and Interrupt Sources of 8/16-bit PPG
Interrupt request flag bit
Interrupt request enable bit
Interrupt source
When a counter borrow occurs on the downcounter, the 8/16-bit PPG sets the counter borrow
detection flag bit (PUF) in the 8/16-bit PPG timer n0/n1 control register (PC) to "1". When the
interrupt request enable bit is enabled (PIE = 1), an interrupt request is output to the interrupt
controller.
In 16-bit PPG mode, the 8/16-bit PPG timer n0 control register (PCn0) is available.
