Move 32-Bit Value from Memory to the MSTF Register
MSTF | CLA status register |
mem32 | 32-bit source memory location |
LSW: mmmm mmmm mmmm mmmm
MSW: 0111 0111 0000 addr
Move from memory to the CLA's status register MSTF. This instruction is most useful when nesting function calls (using MCCNDD).
MSTF = [mem32];
This instruction modifies the following flags in the MSTF register:
Flag | TF | ZF | NF | LUF | LVF |
---|---|---|---|---|---|
Modified | Yes | Yes | Yes | Yes | Yes |
Loading the status register can overwrite all flags and the RPC field. The MEALLOW field is not affected.
This is a single-cycle instruction.
