+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.
