NOTE: When the data length is an odd number
Every command’s total length in byte must be an even number.
If the total length is an odd number, you need to add an extra “FF” at the end of the packet, to make the length an
even number. In the same manner, the length of the acknowledgement data from the IC-R8600 is an even number.
