The checksum is the 8-bit sum of the MSB and LSB of the command plus the (command length) bytes in the buffer. The final sum is the bitwise inversion of the result. Since the length is part of the checksum, the verification cannot take place until the length is written. The checksum and length must be written together as a word to be valid.
