C2510Fx / CC2511Fx  
11.3 CPU Registers  
This section describes the internal registers  
found in the CPU.  
The data pointer select bit, bit 0 in the Data  
Pointer Select register DPS, chooses which  
data pointer to use during the execution of an  
instruction that uses the data pointer, e.g. in  
one of the above instructions.  
11.3.1 Data Pointers  
The CC2510Fx/CC2511Fx has two data pointers,  
DPTR0 and DPTR1, to accelerate the  
movement of data blocks to/from memory. The  
data pointers are generally used to access  
CODE or XDATA space e.g.  
The data pointers are two bytes wide  
consisting of the following SFRs:  
DPTR0 – DPH0:DPL0  
DPTR1 – DPH1:DPL1  
MOVC A,@A+DPTR  
MOV A,@DPTR.

11.3.2 Registers R0 - R7  
bank to be used is selected through the  
Program Status Word PSW.RS[1:0].  
The CC2510Fx/CC2511Fx provides four register  
banks of eight registers each. These register  
banks are in the DATA memory space at  
addresses 0x00-0x07, 0x08-0x0F, 0x10-0x17  
and 0x18-0x1F and are mapped to address  
range 0xFF00 to 0xFF1F in the unified  
memory space. Each register bank contains  
the eight 8-bit register R0 - R7. The register  
11.3.3 Program Status Word  
The Program Status Word (PSW) contains  
several bits that show the current state of the  
CPU. The Program Status Word is accessible  
as an SFR and it is bit-addressable. The PSW  
register contains the Carry flag, Auxiliary Carry  
SWRS055D
