LLWU Pin Enable 1 Register (LLWU_PE1)
LLWU Pin Enable 2 Register (LLWU_PE2)
LLWU Pin Enable 3 Register (LLWU_PE3)
LLWU Pin Enable 4 Register (LLWU_PE4)
LLWU Module Enable Register (LLWU_ME)
LLWU Flag 1 Register (LLWU_F1)
LLWU Flag 2 Register (LLWU_F2)
LLWU Flag 3 Register (LLWU_F3)
LLWU Pin Filter 1 Register (LLWU_FILT1)
LLWU Pin Filter 2 Register (LLWU_FILT2)
All LLWU registers are reset by Chip Reset not VLLS and by
reset types that trigger Chip Reset not VLLS. Each register's
displayed reset value represents this subset of reset types.
LLWU registers are unaffected by reset types that do not trigger
Chip Reset not VLLS. For more information about the types of
reset on this chip, refer to the
