102 / 935 page ![]() Section 2 CPU Rev. 2.00 Mar 09, 2006 page 76 of 906 REJ09B0292-0200 The instruction codes, operation, and execution states of the CPU instructions are listed by classification with the formats listed in below. Instruction Instruction Code Operation Execution Cycles T Bit Indicated by mnemonic Explanation of Symbols OP.Sz SRC, DEST OP: Operation code Sz: Size SRC: Source DEST: Destination Rm: Source register Rn: Destination register imm: Immediate data disp: Displacement* 2 Indicated in MSB ↔ LSB order Explanation of Symbols mmmm: Source register nnnn: Destination register 0000: R0 0001: R1 ......... 1111: R15 iiii: Immediate data dddd: Displacement Indicates summary of operation Explanation of Symbols →, ←: Transfer direction (xx): Memory operand M/Q/T: Flag bits in the SR &: Logical AND of each bit |: Logical OR of each bit ^: Exclusive OR of each bit ~: Logical NOT of each bit <<n: n-bit left shift >>n: n-bit right shift Value when no wait states are inserted* 1 Value of T bit after instruction is executed Explanation of Symbols —: No change Notes: 1. Instruction execution cycles: The execution cycles shown in the table are minimums. The actual number of cycles may be increased when (1) contention occurs between instruction fetches and data access, or (2) when the destination register of the load instruction (memory → register) and the register used by the next instruction are the same. 2. Depending on the instruction’s operand size, scaling is ×1, ×2, or ×4. For details, see the SH-1/SH-2/SH-DSP Software Manual. |
