7.  Normal Function 

7.1 CPU 

7.1.1 CPU Core SFR 

Feature 

  CPU core registers: ACC, B, PSW, SP, DPL, DPH 

Accumulator 

ACC is the Accumulator register. Instruction system adopts A as mnemonic symbol of accumulator. 

B Register 

The B register is used during multiply and divide operations. For other instructions it can be treated as another scratch pad 
register. 

Stack Pointer (SP) 

The Stack Pointer Register is 8 bits special register, It is incremented before data is stored during PUSH, CALL executions and 
it is decremented after data is out of stack during POP, RET,  RETI  executions. The stack may reside  anywhere in on-chip 
internal RAM (00H-FFH). On reset, the Stack Pointer is initialized to 07H causing the stack to begin at location 08H. 

Program Status Word Register (PSW) 

The PSW register contains program status information. 

Data Pointer Register (DPTR) 

DPTR consists  of a high byte (DPH) and a low byte (DPL). Its intended function is to hold a 16-bit address, but it may be 
manipulated as a 16-bit register or as two independent 8-bit registers.
