Table 1
Description of Items in Instruction List
Item
Description
Mnemonic
English upper case and symbol: Described directly in assembler code.
English lower case: Converted in assembler code.
Number of letters after English lower case: Describes bit width in code.
#
Describes number of bytes.
~
Describes number of cycles.
For other letters in other items, refer to table 4.
B
Describes correction value for calculating number of actual states.
Number of actual states is calculated by adding value in the ~section.
Operation
Describes operation of instructions.
LH
Describes a special operation to 15 bits to 08 bits of the accumulator.
Z : Transfer 0.
X : Sign-extend and transfer.
– : No transmission
AH
Describes a special operation to the upper 16-bit of the accumulator.
* : Transmit from AL to AH.
– : No transfer.
Z : Transfer 00H to AH.
X : Sign-extend AL and transfer 00H or FFH to AH.
I
Describes status of I (interrupt enable), S (stack), T (sticky bit), N (negative), Z (zero),
V (overflow), and C (carry) flags.
* : Changes after execution of instruction.
– : No changes.
S : Set after execution of instruction.
R : Reset after execution of instruction.

T
N
Z
V
C
RMW
Describes whether or not the instruction is a read-modify-write type (a data is read out from
memory etc. in single cycle, and the result is written into memory etc.).
* : Read-modify-write instruction
– : Not read-modify-write instruction
Note: Not used to addresses having different functions for reading and writing operations.
