This demo is based on the GD32307C-EVAL-V1.1 board, it explains how to configure the
RTC module. In this demo, RTC peripheral is configured to display calendar. Select LXTAL
as RTC clock source. And the HyperTerminal should be connected to the evaluation board via COM0.
After start-up,get key value from BKP data register or bit RTCSRC of backup domain
control register. If the value is incorrect, the program will ask to set the time on the
HyperTerminal. If the value is correct, by the HyperTerminal set time,the calendar will
be displayed on the HyperTerminal.
The RTC module is in the Backup Domain, and is not reset by the system reset.
