Section 15 Realtime Clock (RTC)
15.3.1
R64CNT indicates the state of the divider circuit between 64 Hz and 1 Hz.
Reading this register, when carry from 128-Hz divider stage is generated, sets the CF bit in the
RTC control register 1 (RCR1) to 1 so that the carrying and reading 64 Hz counter are performed
at the same time is indicated. In this case, the R64CNT should be read again after writing 0 to the
CF bit in RCR1 since the read value is not valid.
After the RESET bit or ADJ bit in the RTC control register 2 (RCR2) is set to 1, the RTC divider
circuit is initialized and R64CNT is initialized to H'00.
R64CNT is not initialized by a power-on reset or manual reset, or in deep standby and software
standby modes.
