34.6.4 DMA, Interrupts and Events

Each interrupt source has its own interrupt flag. The interrupt flag in the Interrupt Flag Status and Clear register (INTFLAG) is set when the interrupt condition is met. Each interrupt can be individually enabled by writing ‘1’ to the corresponding bit in the Interrupt Enable Set register (INTENSET) and disabled by writing ‘1’ to the corresponding bit in the Interrupt Enable Clear register (INTENCLR). An interrupt request is generated when the interrupt flag is set and the corresponding interrupt is enabled. The interrupt request is active until the interrupt flag is cleared, the interrupt is disabled or the I²C is reset. See the INTFLAG (Client) or INTFLAG (Host) register from Related Links for details on how to clear interrupt flags.
