Instruction Set
The instruction set of the CIP-51 System Controller is fully compatible with the standard MCS-51 instruc-
tion set. Standard 8051 development tools can be used to develop software for the CIP-51. All CIP-51
instructions are the binary and functional equivalent of their MCS-51 counterparts, including opcodes,
addressing modes and effect on PSW flags. However, instruction timing is different than that of the stan-
dard 8051.
9.1.1. Instruction and CPU Timing
In many 8051 implementations, a distinction is made between machine cycles and clock cycles, with
machine cycles varying from 2 to 12 clock cycles in length. However, the CIP-51 implementation is based
solely on clock cycle timing. All instruction timings are specified in terms of clock cycles.
Due to the pipelined architecture of the CIP-51, most instructions execute in the same number of clock
cycles as there are program bytes in the instruction. Conditional branch instructions take one less clock
cycle to complete when the branch is not taken as opposed to when the branch is taken. Table 9.1 is the
CIP-51 Instruction Set Summary, which includes the mnemonic, number of bytes, and number of clock
cycles for each instruction.
9.1.2. MOVX Instruction and Program Memory
The MOVX instruction is typically used to access external data memory. The CIP-51 does not support
external data or program memory. In the CIP-51, the MOVX instruction accesses the on-chip program
memory space implemented as re-programmable Flash memory and the 1024 bytes of XRAM (optionally
available on ‘F226/236 and ‘F206). This feature provides a mechanism for the CIP-51 to update program
code and use the program memory space for non-volatile data storage. Refer to Section 10 (Flash Mem-
ory) and Section 11 (External RAM) for further details.
