Note:
1. Three address bytes are only required for the first operation to designate the address to start programming at. Afterwards,
the internal address counter automatically increments, so subsequent Sequential Program Mode operations only require
clocking in of the opcode and the data byte until the Sequential Program Mode has been exited.
