NEC 78K0 Series User Manual page 580

This chapter lists each instruction set of the 78K0/KE2 in table form. For details of each operation and operation
code, refer to the separate document 78K/0 Series Instructions User's Manual (U12326E).
28.1 Conventions Used in Operation List
28.1.1 Operand identifiers and specification methods
Operands are written in the "Operand" column of each instruction in accordance with the specification method of
the instruction operand identifier (refer to the assembler specifications for details). When there are two or more
methods, select one of them. Uppercase letters and the symbols #, !, $ and [ ] are keywords and must be written 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
write 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 specification.
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 Special function register symbol (16-bit manipulatable register even addresses only)
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 0040H to 007FH Immediate data or labels (even address only)
word 16-bit immediate data or label
byte 8-bit immediate data or label
bit 3-bit immediate data or label
RBn RB0 to RB3
Note Addresses from FFD0H to FFDFH cannot be accessed with these operands.
Remark For special function register symbols, see Table 3-6 Special Function Register List.
