/* File: startup_TM4C123GH6PM.c for GNU-ARM
* Purpose: startup file for TM4C123GH6PM Cortex-M4 device.
* Should be used with GCC 'GNU Tools ARM Embedded'
* Version: CMSIS 5.0.1
* Date: 2017-09-13
*
* Modified by Quantum Leaps:
* - Added relocating of the Vector Table to free up the 256B region at 0x0
* for NULL-pointer protection by the MPU.
* - Modified all exception handlers to branch to assert_failed()
* instead of locking up the CPU inside an endless loop.
*
* Created from the CMSIS template for the specified device
* Quantum Leaps, www.state-machine.com
*
* NOTE:
* The function assert_failed defined at the end of this file defines
* the error/assertion handling policy for the application and might
* need to be customized for each project. This function is defined in
* assembly to re-set the stack pointer, in case it is corrupted by the
* time assert_failed is called.
