Each block of data is packed from the lowest order byte first. In the case of multiple-byte data, the least
significant bit is the LSB of the first "data" block, and the most significant bit is the MSB of the final "data"
block.
The following shows an example of how data would be divided for transfer in the case of 32-bit data.
