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 14 ).

Carry flag.
Auxiliary Carry flag for BCD operations.
General purpose Flag 0 available for user.
F0 is not to be confused with the F0 flag in the CESTATUS register.

Overflow flag.
User defined flag.
Parity flag, affected by hardware to indicate odd or even number of one bits in
the Accumulator, i.e., even parity.
Stack Pointer ( SP, SFR 0x81 ):
The stack pointer is a 1-byte register initialized to 0x07 after reset. This register is incremented before
PUSH and CALL instructions, causing the stack to begin at location 0x08.
Data Pointer:
The data pointers ( DPTR and DPRT1 ) are 2 bytes wide. The lower part is DPL (SFR 0x82) and DPL1 (SFR
0x84), respectively. The highest is DPH (SFR 0x83) and DPH1 (SFR 0x85), respectively. The data pointers
can be loaded as two registers (e.g., MOV DPL,#data8). They are 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 ( PC ) is 2 bytes wide and initialized to 0x0000 after reset. This register is incremented
when fetching operation code or when operating on data from program memory.
