Description |
Example |
MOV destination,source |
Copies the constant or the value from the address pointed by source to the address
pointed by destination, destination cannot be a constant. |
MOV #5,23 - Copies 23 to the memory cell with address 5. MOV R1,#15 - Copies value from
memory cell with address 15 to register R1. |
ADD destination,source |
Adds destination and source and stores the result in register or address pointed
by destination, because of that destination cannot be a constant. |
ADD R0,5 - Adds the content of register R0 and constant 5 and stores the result in register R0.
|
SUB destination,source |
Subtracts source from destination and stores the result in register or address
pointed by destination, because of that destination cannot be a constant. |
SUB R0,5 - Subtracts 5 from the content of register R0 and stores the result in register R0.
|
MUL destination,source |
Multiplies destination and source and stores the result in register or address
pointed by destination, because of that destination cannot be a constant. |
MUL R0,5 - Multiplies the content of register R0 and constant 5 and stores the result in
register R0. |
DIV destination,source |
Divides destination by source and stores the result in register or address pointed
by destination, because of that destination cannot be a constant. |
DIV R0,5 - Divides the content of register R0 by constant 5 and stores the result in register
R0. |
