symbols used.
Table B.7-1 Description of Items in the Instruction List
Item
• Uppercase, symbol: Represented as is in the assembler.
• Lowercase: Rewritten in the assembler.
Mnemonic
• Number of following lowercase: Indicates bit length in the instruction.
#
Indicates the number of bytes.
Indicates the number of cycles.
to
For alphabetic characters in the items, see Table B.5-1 and Table B.5-2.
• Indicates the number of times a register access is performed during instruction execution.
RG
• The number is used to calculate the correction value for CPU intermittent operation.
• Indicates the correction value used to calculate the actual number of cycles during
instruction execution.
B
• The actual number of cycles during instruction execution can be determined by adding the
value in the ~ column to this value.
Operation
Indicates the instruction operation.
Indicates the special operation for bit 15 to bit 08 of the accumulator.
• Z: Transfers 0.
LH
• X: Transfer with sign expansion
• -: No transfer
Indicates the special operation for the first 16 bits of the accumulator.
• *: Transfers from AL to AH.
• -: No transfer
AH
• Z: Transfers 00 to AH.
• X: Transfers AH to 00
I
S
I (interrupt enable), S (stack), T (sticky bit), N (negative) indicates the status of each flag of
Z (zero), V (overflow) and C (carry).
T
• *: Changes upon instruction execution.
N
• -: No change.
Z
• Z: Set upon instruction execution.
• X: Reset upon instruction execution.
V
C
Indicates whether it is a read-modify-write instruction (that reads data from memory and
write the results into memory by the 1 instruction).
• *: Read-modify-write instruction
RMW
• -: Not a read-modify-write instruction
Note: Cannot be used for the address that has different meanings between read and write
