CHAPTER 30 INSTRUCTION SET
CHAPTER 30 INSTRUCTION SET
This chapter lists the instructions in the 78K0R microcontroller instruction set. For details of each operation and
operation code, refer to the separate document 78K0R Microcontrollers Instructions User’s Manual (U17792E).
Remark The shaded parts of the tables in Table 30-5 Operation List indicate the operation or instruction format that
is newly added for the 78K0R microcontrollers.
30.1 Conventions Used in Operation List
30.1.1 Operand identifiers and specification methods
Operands are described in the “Operand” column of each instruction in accordance with the description method of the
instruction operand identifier (refer to the assembler specifications for details). When there are two or more description
methods, select one of them. Alphabetic letters in capitals and the symbols, #, !, !!, $, $!, [ ], and ES: are keywords and
are described as they are. Each symbol has the following meaning.
• #: Immediate data specification
• !: 16-bit absolute address specification
• !!: 20-bit absolute address specification
• $: 8-bit relative address specification
• $!: 16-bit relative address specification
• [ ]: Indirect address specification
• ES: Extension address specification
In the case of immediate data, describe an appropriate numeric value or a label. When using a label, be sure to
describe the #, !, !!, $, $!, [ ], and ES: symbols.
For operand register identifiers, r and rp, either function names (X, A, C, etc.) or absolute names (names in
parentheses in the table below, R0, R1, R2, etc.) can be used for description.
