Section 16 Realtime Clock (RTC)
16.4
16.4.1
During the RTC count operation (RCR2 bits 0 = 1), the following registers cannot be written.
RSECCNT, RMICNT, RHRCNT, RDAYCNT, RWKCNT, RMONCNT, and RYRCNT
To write these registers, the RTC count operation should be stopped.
16.4.2
Figure 16.6 shows the periodic interrupt function setting flow.
Periodic interrupts can be generated with the period specified by the periodic interrupt enable flag
(PES) in the RTC control register (RCR2). When the time period specified by PES passed, the
periodic interrupt flag (PEF) is set to 1.
PEF is cleared to 0 when PES is set and a periodic interrupt is generated. The periodic interrupt
generation can be checked by reading this bit, but is usually checked by the interrupt function.
