Real-time clock/calendar
8.4 Time and date registers
The majority of the registers are coded in the BCD format to simplify application use.
8.4.1 Register VL_seconds
[1]
Start-up value.
8.4.1.1
Voltage-low detector and clock monitor
The PCF8563 has an on-chip voltage-low detector (see Figure 7). When VDD drops below
Vlow, bit VL in the VL_seconds register is set to indicate that the integrity of the clock
information is no longer guaranteed. The VL flag can only be cleared by using the
interface.
