Note Holds the value before reset.
Use these registers to set the values to be compared with values in the ElapsedTime registers.
A write operation is valid once values have been written to all registers (ECMPLREG, ECMPMREG, and
ECMPHREG).
When setting these registers again, wait until at least 100 µ s (three cycles of 32.768 kHz clock) have elapsed after
the first setting.
