Interrupt Conditions
The interrupt status bits found in the ERR_RST_EVNT (0x0270) can be cleared by writing to the ICCR register (0x0278) in the same manner as other interrupts. However, in order for new event detection and interrupt generation to occur for these special interrupts, additional register bits must be cleared. The following table notes the additional interrupt source register bits that need to be cleared and the appropriated sequence. These are all the bits that can cause the ERR_RST_EVNT status bits to be set
