Variable Documentation

◆ SERCOM0_InterruptHandler

volatile SERCOM_INTERRUPT_HANDLER SERCOM0_InterruptHandler

extern

Interrupt handler for SERCOM0 peripheral.

This variable holds the function pointer to the current interrupt handler for the SERCOM0 module. It should be assigned to a function that matches the SERCOM_INTERRUPT_HANDLER signature. The variable is declared as volatile because it may be modified by interrupt service routines.
