8.3.1.
Following are descriptions of SFRs related to the operation of the CIP-51 System Controller. Reserved bits should
not be set to logic l. Future product versions may use these bits to implement new features in which case the reset
value of the bit will be logic 0, selecting the feature’s default state. Detailed descriptions of the remaining SFRs are
included in the sections of the datasheet associated with their corresponding system function.
Bits 7-0: SP: Stack Pointer.
Bits 7-0: DPL: Data Pointer Low.
Bits 7-0: DPH: Data Pointer High.

Register Descriptions
The stack pointer holds the location of the top of the stack. The stack pointer is
incremented before every PUSH operation. The SP register defaults to 0x07 after reset.
The DPL register is the low byte of the 16-bit DPTR. DPTR is used to access indirectly
addressed RAM and Flash Memory.
The DPH register is the high byte of the 16-bit DPTR. DPTR is used to access indirectly
addressed RAM and Flash Memory.
