14.6.6 Interrupt Flag Status and Clear
Note:
- Writing a one to any bit will clear the corresponding interrupt flag. Writing a zero has no effect.
- Writes to this register while the SYNCBUSY.SWRST is asserted with cause a bus error.
Note: Subsequent to an interrupt flag being cleared, the flag must be read back to
verify the clear before exiting the ISR. Failure to do this can result in duplicate
interrupts.
