45.6.4 Interrupt Flag Status and Clear
Note:
- Access to this register is limited to 32-bit width. Byte level access is not allowed.
- Reserved bits must always be written as ‘0’.
- Interrupt flags must be cleared and then read back to confirm they are cleared before exiting the ISR to avoid double interrupts.

Bit 1 – DRP Data Remanence Prevention Complete Interrupt
This flag is set when the data remanence prevention routine has completed, and an interrupt request will be generated if INTENSET.DRP bit (INTENSET <1>) is set to '1'.
Writing a ‘0’ to this bit has no effect.
Writing a ‘1’ to this bit clears the data remanence prevention complete interrupt flag.
Bit 0 – ERR TRAM Read Error Interrupt
This flag is set when an error is detected in the TRAM readout, and an interrupt request will be generated if INTENSET.ERR bit (INTENSET <0>) is set to '1'.
Writing a ‘0’ to this bit has no effect.
Writing a ‘1’ to this bit clears the TRAM read error interrupt flag.
