1. EXI2ES and EXI3ES must be configured as 01b because RTC interrupt request lines are rising edge
active.
2. Alarm interrupt request line (RTCAI) is linked with EXI3ES
3. Timed interrupt request line (RTCSI) is linked with EXI2ES

EXIxES
(x = 7 to 0)
External interrupt x edge selection field (x = 7...0)
00: Fast external interrupts disabled (standard mode). EXxIN pin not
taken into account for entering/exiting power-down mode.
01: Interrupt on positive rising edge. Power-down mode is entered if
EXiIN = 0 and exited if EXxIN = 1 (referred as ‘high’ active level).
10: Interrupt on negative falling edge. Power-down mode is entered if
EXiIN = 1 and exited if EXxIN = 0 (referred as ‘low’ active level).
11: Interrupt on any edge (rising or falling). Power-down mode is
always entered. It is exited if the EXxIN level changes.
