+title: Real Time Clock of the Sophgo CV1800 SoC
+
+description:
+ Real Time Clock (RTC) is an independently powered module
+ within the chip, which includes a 32KHz oscillator and a
+ Power On Reset/POR submodule. It can be used for time display
+ and timed alarm generation. In addition, the hardware state
+ machine provides triggering and timing control for chip
+ power on, off, and reset.
