7. INSTRUCTION SET
Describe an operand in the operand field of each instruction according to the description method of the
instruction (for details, refer to the Assembler Specifications). Some instructions have two or more
operands. Select one of them. Uppercase characters, +, –, #, $, !, [, and ] are keywords and must be
described as is.
Describe an appropriate numeric value or label as immediate data. To describe a label, be sure to
describe #, $, !, [, or ].

RP0, RP1, RP2, RP3, RP4, RP5, RP6, RP7
rp1
RP0, RP1, RP2, RP3, RP4, RP5, RP6, RP7
rp2
DE, HL, VP, UP
sfr
Special function register symbol (Refer to Table 2-1.)
sfrp
Special function register symbol (register that can be manipulated in 16-bit units. Refer to Table
2-1.)
post
RP0, RP1, RP2, RP3, RP4, RP5/PSW, RP6, RP7
(More than one symbol can be described. However, RP5 can be described only for PUSH and
POP instructions, and PSW can be described only for PUSHU and POPU instructions.)
mem
[DE], [HL], [DE +], [HL +], [DE –], [HL –], [VP], [UP]
; register indirect mode
[DE + A], [HL + A], [DE + B], [HL + B], [VP + DE], [VP + HL] ; based indexed mode
[DE + byte], [HL + byte], [VP + byte], [UP + byte], [SP + byte] ; based mode
word[A], word[B], word[DE], word[HL]
; indexed mode
saddr
saddrp
FE20H-FF1FH immediate data or label
FE20H-FF1EH immediate data (however, bit0 = 0) or label (manipulated in 16-bit units)
$ addr16
! addr16
addr11
addr5
word
byte
bit
n
0000H-FDFFH immediate data or label; relative addressing
0000H-FDFFH immediate data or label; immediate addressing
(However, up to FFFFH can be described for MOV instruction. Only FE00H-FEFFH can be
described for MOVTBLW instruction.)
800H-FFFH immediate data or label
40H-7EH immediate data (however, bit0 = 0)^Note or label
16-bit immediate data or label
8-bit immediate data or label
3-bit immediate data or label
3-bit immediate data (0-7)
Note Do not access bit0 = 1 (odd address) in word units.
Remarks 1. rp and rp1 are the same in terms of register name that can be described but are different in code
to be generated.
2. r, r1, rp, rp1, and post can be described in absolute name (R0-R15, RP0-RP7) and function name
(X, A, C, B, E, D, L, H, AX, BC, DE, HL, VP, and UP).
3. Immediate addressing can address the entire space. Relative addressing can address only a
range of –128 to +127 from the first address of the next instruction.
