[Syntax]

MOVCO src, dest

[Operation]

if (LI == 1) {dest=src;src=0;}

else { src=1; }

LI = 0;

[Function]

When the LI flag is 1, data in src (register) is stored in dest (memory) and the LI flag and src are cleared to 0.

When the LI flag is 0, data is not stored in src. Instead, 1 is set to src.

The LI flag is in the inside of CPU. The bit can be accessed only by MOVCO, MOVLI, RTE or RTFI instruction.

Customer can not access the LI flag directly.

Before executing the MOVCO instruction, execute the MOVLI instruction for the same address.

You can assemble assembly-language code that includes this instruction if you have specified the assembler option -isa with selection of the instruction set of the RXv2 or a later version.
