Figure 26.17 CEC Function Interrupt
For the interrupt request timing, refer to the operation examples.
For interrupt control, refer to 14.7 “Interrupt Control”. Table 26.11 lists CEC Function Interrupt-Associated
Registers.

The CEC function shares the interrupt vectors and the interrupt control registers with other peripheral
functions. To use CEC1 interrupt, set the IFSR33 bit in the IFSR3A register to 1 (CEC1). To use CEC2
interrupt, set the IFSR34 bit in the IFSR3A register to 1 (CEC2).
