Description
Periodic Interrupt Flag
Indicates interrupt generation at the interval specified
by bits PES2–PES0. When this flag is set to 1, a
periodic interrupt is generated.
0: Interrupt is not generated at interval specified by bits
PES2–PES0
[Clearing condition]
When 0 is written to PEF
1: Interrupt is generated at interval specified by bits
PES2–PES0
[Setting conditions]
Generation of interrupt at interval specified by bits
PES2–PES0
When 1 is written to PEF
Periodic Interrupt Enable
These bits specify the period for periodic interrupts.
000: No periodic interrupt generation
001: Periodic interrupt generated at 1/256-second
010: Periodic interrupt generated at 1/64-second
011: Periodic interrupt generated at 1/16-second
100: Periodic interrupt generated at 1/4-second
101: Periodic interrupt generated at 1/2-second
110: Periodic interrupt generated at 1-second intervals
111: Periodic interrupt generated at 2-second intervals
Oscillator Enable
Controls the operation of the RTC's crystal oscillator.
0: RTC crystal oscillator is halted
1: RTC crystal oscillator is operated
