3. Instruction Set

3-17

1. X, Y, M, and S are defined as bit devices which indicate ON/OFF status.

2. 16-bit (or 32-bit) devices T, C, D, and registers E, F are defined as word devices.

3. “Kn” can be placed before bit devices X, Y, M and S to make it a word device for performing

word-device operations. (n = 1 refers to 4 bits. For 16-bit instruction, n = K1 ~ K4; for 32-bit

instruction, n = K1 ~ K8). For example, K2M0 refers to 8 bits, M0 ~ M7.

K2M0

D10

MOV

When X0 = ON, the contents in M0 ~ M7 will be

moved to b0 ~b7 in D10 and b8 ~b15 will be

set to “0”.

Flags

1. General Flags

The flags listed below are used for indicating the operation result of the application

instruction:

M1020: Zero flag

M1021: Borrow flag

M1022: Carry flag

M1029: Execution of instruction is completed

All flags will turn ON or OFF according to the operation result of an instruction. For example,

the execution result of instructions ADD/SUB/MUL/DVI will affect the status of M1020 ~

M1022. When the instruction is not executed, the ON/OFF status of the flag will be held. The

status of the four flags relates to many instructions. See relevant instructions for more

details.
