XOR Calculation
The checksum, which is 8-bits wide, is generated by splitting the data into bytes and then performing an XOR of the bytes.
Example of an XOR Calculation—24-Bit Word: 0x654321 (Eight Command Bits and 16-Bit Data)
Using the previous example,
Divide into three bytes: 0x65, 0x43, and 0x21
01100101 0x65
01000011 0x43
00100110 XOR result
00100001 0x21
00000111 CRC
