Field
Chapter 15 Low-leakage wake-up unit (LLWU)
LLWU_PE3 field descriptions (continued)
Description
10 External input pin enabled with falling edge detection
11 External input pin enabled with any change detection
15.3.4 LLWU Pin Enable 4 Register (LLWU_PE4)
LLWU_PE4 contains the bit field to enable and select the edge detect type for the
external wakeup input pins LLWU_P15-LLWU_P12.
NOTE
This register is unaffected by wakeup from low leakage modes
(exit from LLS via RESET or any exit from VLLS).
Address: LLWU_PE4 is 4007_C000h base + 3h offset = 4007_C003h
