15.5
15.5.1
The following RTC registers cannot be written to during an RTC count (while the START bit = 1
in RCR2).
RSECCNT, RMINCNT, RHRCNT, RDAYCNT, RWKCNT, RMONCNT, RYRCNT
The RTC count must be stopped before writing to any of the above registers.
15.5.2
The method of using the periodic interrupt function is shown in figure 15.6.
A periodic interrupt can be generated periodically at the interval set by the periodic interrupt flag
(PES0−PES2) in RCR2. When the time set by the PES0−PES2 has elapsed, the PEF is set to 1.
The PEF is cleared to 0 upon periodic interrupt generation or when the periodic interrupt flag
(PES0 to PES2) is set. Periodic interrupt generation can be confirmed by reading this bit, but
normally the interrupt function is used.
15.5.3
When a transition to standby mode is made after registers in the RTC are set, sometimes counting
is not performed correctly. In case the registers are set, be sure to make a transition to standby
mode after waiting for two RTC clocks or more.
