Sync to Main 100ms time stamp & added Reinitialization of globals after startup
Added function to synchronize RTE to the timestamp provided by Main 100ms callback. This was introduced to compensated small shifts in execution and program flow shifts (for example during long operation times)

/** ****************************************************************************** * @file stm32f4xx_ll_fsmc.c * @author MCD Application Team * @brief FSMC Low Layer HAL module driver. * * This file provides firmware functions to manage the following * functionalities of the Flexible Static Memory Controller (FSMC) peripheral memories: * + Initialization/de-initialization functions * + Peripheral Control functions * + Peripheral State functions * @verbatim ============================================================================== ##### FSMC peripheral features ##### ============================================================================== [..] The Flexible static memory controller (FSMC) includes two memory controllers: (+) The NOR/PSRAM memory controller (+) The NAND/PC Card memory controller [..] The FSMC functional block makes the interface with synchronous and asynchronous static memories, SDRAM memories, and 16-bit PC memory cards. Its main purposes are: (+) to translate AHB transactions into the appropriate external device protocol. (+) to meet the access time requirements of the external memory devices. [..] All external memories share the addresses, data and control signals with the controller. Each external device is accessed by means of a unique Chip Select. The FSMC performs only one access at a time to an external device. The main features of the FSMC controller are the following: (+) Interface with static-memory mapped devices including: (++) Static random access memory (SRAM). (++) Read-only memory (ROM). (++) NOR Flash memory/OneNAND Flash memory. (++) PSRAM (4 memory banks). (++) 16-bit PC Card compatible devices. (++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of data. (+) Independent Chip Select control for each memory bank. (+) Independent configuration for each memory bank. @endverbatim ****************************************************************************** * @attention * * <h2><center>© COPYRIGHT(c) 2017 STMicroelectronics</center></h2> * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
