An Accumulator is a very fast register inside a processor that acts as a mathematical scratch pad.
The 65c816's accumulator can be either 8 or 16 bits in size, as configured by the M flag.
The high byte is still retained even when the accumulator is 8 bits wide.
The SPC700's accumulator is always 8 bits wide.
