Description:
Copies the content of the op1 source register in a Data RAM line defined by the 6-bit
Data RAM address Dram.
The operand Dram can be identified with a univocal label. The compiler automatically
substitutes the 'define' label (if used) with the suitable Data RAM address.
The Data RAM address is accessed according to the Boolean operand Ofs using the:
Immediate addressing mode (IM).
Indexed addressing mode (XM). In that case, the address base is added to the address
Dram. The address base is set using the stab instructions.
Assembler syntax:
store op1 Dram Ofs;
Operands:
•
op1 – One of the registers listed in the operand
•
Dram – Operand defines the 6-bit DRAM address
•
Ofs – Operands sets data RAM addressing mode
