Accumulator (ACC, A, SFR 0x E0):
ACC is the accumulator register. Most instructions use the accumulator to hold the operand. The mnemonics
for accumulator-specific instructions refer to accumulator as A, not ACC.
B Register (SFR 0xF0):
The B register is used during multiply and divide instructions. It can also be used as a scratch-pad register to
hold temporary data.
Program Status Word (PSW, SFR 0xD0):
This register contains various flags and control bits for the selection of the register banks (see Table 13).
