9.6.3 Stop Mode Recovery
When the MCU recovers from stop2 mode a reset sequence is initiated. All Control Registers should be
re-written before the stop2 recovery acknowledge bit is set. The Registers LCDBPEN, LCDPEN and the
LCDWF retain their values upon stop2 recovery and do not need to be re-written.
