z Bits 7:1 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always write these
bits to zero when this register is written. These bits will always return zero when read.
z Bit 0 – EW: Early Warning
This flag is set when an Early Warning interrupt occurs, as defined in EWCTRL.EWOFFSET.
Writing a zero to this bit has no effect.
Writing a one to this bit clears the Early Warning interrupt flag.
