PER2 - Period Register 2
PER1 - Period Register 1
PER0 - Period Register 0
COMP3 - Compare Register 3
COMP2 - Compare Register 2
The COMP0, COMP1, COMP2 and COMP3 registers represents the 32-bit value COMP. COMP
is constantly compared with the counter value (CNT). A compare match will set the COMPIF in
the INTFLAGS register, and the optional interrupt is generated.
If the COMP value is higher than the PER value, no RTC Compare Match interrupt requests or
events will be generated
After writing the high byte of the COMP register, the condition for setting OVFIF and COMPIF,
as well as the Overflow and Compare Match Wakeup condition, will be disabled for the following
two RTC clock cycles.
