WKUP pin rising edge (WKPOL = 1)
Device wakes up and sets WKUP flag
HIGH.
WKUP pin falling edge hystersis
(WKPOL = 1) sets WKUP flag LOW (does
not automatically enter sleep mode)
Resistance from WKUP pin to VSS
(WKPOL = 1)
WKUP pin falling edge (WKPOL = 0)
Device wakes up and sets WKUP flag
HIGH.
WKUP pin rising edge hysteresis
(WKPOL = 0) sets WKUP flag LOW (does
not automatically enter sleep mode)
Delay after voltage on WKUP pin crosses
the threshold (rising or falling) before
activating the WKUP bit.
