; * @file startup_efm32pg1b.s for IAR ARM assembler
; * @brief CMSIS Cortex-M4F Core Device Startup File for TM4C123GH6PM
; * @version CMSIS 5.5.1
; * @date 13 May 2019
; *
; * @description
; * 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.

; The function assert_failed defines the error/assertion handling policy
; for the application. After making sure that the stack is OK, this function
; calls Q_onAssert, which should NOT return (typically reset the CPU).
;
; NOTE: the function Q_onAssert should NOT return.
;
; The C proptotype of the assert_failed() and Q_onAssert() functions are:
; void assert_failed(char const *file, int line);
; void Q_onAssert (char const *file, int line);
