Data Movement Instructions Section 3-8
Description Transfers S to D. If S is a constant, the value can be used for a data setting.
MOV(021) has an immediate refreshing variation (!MOV(021)). An external
input bits can be specified for S and external output bits can be specified for
D. Input bits used for S will refreshed just before, and output bits used for D
will be refreshed just after execution unless the bits are allocated to a Group-2
High-density I/O Unit, High-density Special I/O Unit, or a Unit mounted in a
SYSMAC BUS Remote I/O Slave Rack.
