* Trigger=Yes: When all PM_TRIG.TRIG_MSK_* bits are set '1', REGISTER_0 will be written immediately during
a write operation. If any PM_TRIG.TRIG_MSK_* bits are cleared ('0'), REGISTER_0 will not be updated to the
new value after a write operation only after an unmasked PM_TRIG.TRIG_* bit is subsequently written to a '1'.
