Xinje XD Series - Free communication example


When the buffer number is 8 bits, the received data is only stored in low bytes, so
D200 = the number of bytes to be received * 2, for example, to receive 8 bytes of data,
stored in the low bytes of the eight registers D20-D27 in turn, at this time, D200
should be set to 16.

When the buffer number is16 bits, the received data is stored in a complete register,
so D200 = the number of bytes to be received, for example, to receive 8 bytes of data,
stored in the four registers of D20-D23 in turn, at this time, D200 should be set to 8.
And when receiving, low bytes are before high bytes.
