582CHAPTER 28 INSTRUCTION SET28.1 Legends Used in Operation List28.1.1 Operand identifiers and description methodsOperands are described in “Operand” column of each instruction in accordance with the description method of theinstruction operand identifier (refer to the assembler specifications for detail). When there are two or more descriptionmethods, select one of them. Alphabetic letters in capitals and symbols, #, !, $ and [ ] are key words and must bedescribed as they are. Each symbol has the following meaning.• # : Immediate data specification• ! : Absolute address specification• $ : Relative address specification• [ ] : Indirect address specificationIn the case of immediate data, describe an appropriate numeric value or a label. When using a label, be sure todescribe the #, !, $, and [ ] symbols.For operand register identifiers, r and rp, either function names (X, A, C, etc.) or absolute names (names inparentheses in the table below, R0, R1, R2, etc.) can be used for description.Table 28-1.
