13.4
13.4.1
The following RTC registers cannot be written to during an RTC count (while bit 0 = 1 in RCR2).
RSECCNT, RMINCNT, RHRCNT, RDAYCNT, RWKCNT, RMONCNT, RYRCNT
The RTC count must be halted before writing to any of the above registers.
13.4.2
The method of using the periodic interrupt function is shown in figure 13.6.
A periodic interrupt can be generated periodically at the interval set by the periodic interrupt
enable flag (PES) in RTC control register 2 (RCR2). When the time set by the periodic interrupt
enable flag (PES) has elapsed, the periodic interrupt flag (PEF) is set to 1.
The periodic interrupt flag (PEF) is cleared to 0 upon periodic interrupt generation when the
periodic interrupt enable flag (PES) is set. Periodic interrupt generation can be confirmed by
reading this bit, but normally the interrupt function is used.
13.4.3
Before switching the RTC to module standby, access at least one among the registers RTC, SCI,
and TMU.
