&par Example Description

This example shows how to use a DMA channel to transfer a word data buffer from
FLASH memory to embedded SRAM memory.

DMA2 Stream0 channel0 is configured to transfer the contents of a 32-word data
buffer stored in Flash memory to the reception buffer declared in RAM.Then compare 
the data of Flash memory with the data of RAM.
In the end, result of transfer will displayed on serial assistant through USART1.

The USART1 is configured as follows:
    - TX:PA9, RX:PA10
    - BaudRate = 115200 baud
    - Word Length = 8 Bits
    - One Stop Bit
    - No parity
    - Hardware flow control disabled (RTS and CTS signals)
    - Receive and transmit enabled

APM32A407MINI board's LEDs can be used to monitor the transfer status:
 - LED2 is ON when the transfer is pass.
 - LED3 is ON when the transfer is fail.
