16.3.5 LLWU Module Enable register (LLWU_ME)
LLWU_ME contains the bits to enable the internal module flag as a wakeup input source
for inputs MWUF7-MWUF0.
NOTE
This register is reset on Chip Reset not VLLS and by reset
types that trigger Chip Reset not VLLS. It is unaffected by reset
types that do not trigger Chip Reset not VLLS. See the
Introduction details for more information.
Address: LLWU_ME is 4007_C000h base + 4h offset = 4007_C004h
