  This demo is based on the GD32H759I-EVAL-V1.1 board, it shows how to use interrupt to
read and write the memory array through MDIO interface.

  The memory array is initialized with 0x0 to 0x7. To write to the memory array, the host
should send an address frame followed by a write data frame. To read the memory array, the 
host should send an address frame followed by a read frame. Post read increment frames are
also supported.
  NOTE: MDIO requires a pull-up resistor.
