6. OVERVIEW OF THE INSTRUCTION SET
The
μ
PD78P9014 instruction set is shown in the table below.
6.1 Legend
6.1.1 Operand identifiers and methods of use
Operands are described in “Operand” column of each instruction in accordance with the description method of the
instruction operand identifier (refer to the assembler specifications for detail). When there are two or more description
methods, select one of them. Alphabetic letters in capitals and symbols, #, !, $, and [ ] are keywords and must be
described as they are. Each symbol has the following meaning.
# : Immediate data specification
! : Absolute address specification
$
[ ] : Indirect address specification
: Relative 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 [ ] 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.
