+/* Demo specific macros that allow the application writer to insert code to be\r
+executed immediately before the MCU's STOP low power mode is entered and exited\r
+respectively. These macros are in addition to the standard\r
+configPRE_SLEEP_PROCESSING() and configPOST_SLEEP_PROCESSING() macros, which are\r
+called pre and post the low power SLEEP mode being entered and exited. These\r
+macros can be used to turn turn off and on IO, clocks, the Flash etc. to obtain\r
+the lowest power possible while the tick is off. See the comments at the top of\r
+main_low_power.c and in STM32L_low_power_tick_management.c. */\r
