17.5 Operational Description
17.5.1
The sec. counter operation must be taken into account when using the RTC.
Reading clock data
The RTC incorporates a sec. counter that generates an 1Hz signal from a 32.768 KHz signal.
1. Using 1Hz interrupt
2. Using pair reading
counter. Data can be read correctly if reading data after 1Hz interrupt occurred.
operates carry during reading. To ensure correct data reading, read the clock data twice
as shown below. A pair of data read successively needs to match.
The 1Hz interrupt is generated being synchronized with counting up of the sec.
There is a possibility that the clock data may be read incorrectly if the internal counter
