28 Registers
The table below shows the memory mapping for the configuration registers in CC2520.
The FREG registers are accessible with the REGRD and REGWR instructions. Registers in address space
0x000 to 0x01F (marked with gray) are also accessible with the BSET and BCLR instructions.
The SREG registers are only accessible with the MEMRD and MEMWR instructions.
Please also refer to Figure 11: CC2520 memory map for information on the rest of the address range.

NOTE: When accessing unmapped addresses a MEMADDR_ERROR exception will be generated. This is
valid for address space from 0x064 to 0x079 and addresses above 0x07F. Other unmapped addresses like
i.e. 0x003 will not generate a MEMADDR_ERROR.
