10.3. CIP-51 Register Descriptions
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 sys-
tem function.
Notes on Registers, Operands and Addressing Modes:
Rn —Register R0–R7 of the currently selected register bank.
@Ri —Data RAM location addressed indirectly through R0 or R1.
rel —8-bit, signed (two’s complement) offset relative to the first byte of the following instruction. Used by
SJMP and all conditional jumps.
direct —8-bit internal data location’s address. This could be a direct-access Data RAM location (0x00–
0x7F) or an SFR (0x80–0xFF).
#data —8-bit constant
#data16 —16-bit constant
bit —Direct-accessed bit in Data RAM or SFR
addr11 —11-bit destination address used by ACALL and AJMP. The destination must be within the
same 2 kB page of program memory as the first byte of the following instruction.
addr16 —16-bit destination address used by LCALL and LJMP. The destination may be anywhere within
the 64 kB program memory space.
There is one unused opcode (0xA5) that performs the same function as NOP.
