Module gd32vf103xx_hal::backup_domain [−][src]
Expand description
Registers that are not reset as long as Vbat or Vdd has power.
The registers retain their values during wakes from standby mode or system resets. They also
retain their value when Vdd is switched off as long as V_BAT is powered.
The backup domain also contains tamper protection and writes to it must be enabled in order
to use the real time clock (RTC).
Write access to the backup domain is enabled using the BKP::configure(rcu, &mut pmu)
function.
