Parameters:

pBuffer1,pBuffer2,:	buffers to be compared.
BufferLength,:	buffer's length

Return values:

PASSED,: pBuffer1 identical to pBuffer2 FAILED: pBuffer1 differs from pBuffer2

< At this stage the microcontroller clock setting is already configured, this is done through SystemInit() function which is called from startup file (startup_stm32f0xx.s) before to branch to application main. To reconfigure the default setting of SystemInit() function, refer to system_stm32f0xx.c file
