Accumulator (ACC, A): 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: The B
scratch-pad register to hold temporary data.
Program Status Word (
Stack Pointer (SP
incremented before PUSH and CALL instructions, causing the stack to begin at location 0x08.
Data Pointer: The data pointer (
It can be loaded as two registers (e.g. MOV DPL,#data8). It is generally used to access external code or
data space (e.g. MOVC A,@A+DPTR or MOVX A,@DPTR respectively).
Program Counter: The program counter (
register is incremented when fetching operation code or when operating on data from program memory.
