28.1 Legends Used in Operation List
28.1.1 Operand identifiers and description methods
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 key words and must be
described as they are. Each symbol has the following meaning.
• # : Immediate data specification
• !
: Absolute address specification
• $ : Relative address specification
• [ ] : Indirect 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.
Table 28-1. Operand Identifiers and Description Methods
Identifier
r
X (R0), A (R1), C (R2), B (R3), E (R4), D (R5), L (R6), H (R7),
rp
AX (RP0), BC (RP1), DE (RP2), HL (RP3)
sfr
Special-function register symbol
sfrp

saddr
FE20H to FF1FH Immediate data or labels
saddrp
FE20H to FF1FH Immediate data or labels (even address only)
addr16
0000H to FFFFH Immediate data or labels
(Only even addresses for 16-bit data transfer instructions)
addr11
0800H to 0FFFH Immediate data or labels
addr5

Note
Addresses from FFD0H to FFDFH cannot be accessed with these operands.
Remark
For special-function register symbols, refer to Table 5-3 Special-Function Register List.
