* File main.c
* Owner David Tosenovjan
* Version 0.1
* Date May-31-2023
* Classification General Business Information
********************************************************************************
* Detailed Description:
* The purpose of this example is show how to keep data in SRAM memory over SW
* reset.
* INIT_Derivative (file MPC5607B_HWInit.c) is modified to skip ECC RAM
* initialization for SW reset source. Linker command file defines my_ram
* section, a data being kept over reset are accesses as address pointer to this
* location. After initialization SW resets are periodically triggered,
* incrementing data on address test_address_3.
