Backup Mode
The backup mode is established by setting both EOSCEN and EXRS low. In this mode, the low power
consumption can be achieved by stopping all oscillators except for RTC oscillator during the reset interval.
Although all registers are initialized, the SRAM contents in backup area are held.
In order to cancel this mode (reset cancellation), set EOSCEN high at first and then set EXRS high after the
oscillation stabilization time and PLL lock time have passed. It needs 100ms or more.
See Initialization section.
