  This example is based on the GD32G553Q-EVAL-V1.0 board, it provides a
description of MPU's functional attributes.The MPU's functional attributes
by configuring the SRAM's fixed start area 0x20002000 in read-only mode.
You wrote data to this area by KEY_A, LED1 turn on, and the program was
interrupted due to memory management errors.Similarly, if you set the fixed
start area 0x8002000 of the FLASH to write only and press KEY_B to read data
in this area, LED2 turn on, the program will be interrupted due to a memory
management error.When the code into the memory management error is interrupted,
it will print out the relevant information through the USART0 interface.
