■ How to Read the Instruction Lists

1.Instruction name.

An asterisk (*) indicates an extended instruction that is not contained in the CPU specifications and

is obtained by extension of or addition to the assembler.

2.Symbols indicating addressing modes that can be specified for the operand.

3.Instruction format.

4.Instruction code in hexadecimal notation.

5.Number of machine cycles. The minimum for a, b, c, and d is 1 cycle.

a: Memory access cycle that may be extended by the Ready function., b: Memory access cycle that

may be extended by the Ready function. However, the cycle is interlocked if a direct instruction

references a register intended for an LD operation, increasing the number of execution cycles by 1.,

c: Interlocked if the direct instruction is an instruction that reads or writes to R15, SSP, or USP, or

an instruction in instruction format A. The number of execution cycles increases by 1 or 2., d:

Interlocked if the direct instruction references MDH/MDL. The number of execution cycles

increases to 2.

6.Indicates a flag change.

Flag change C: Change -: No change 0: Clear 1: Set
