Bitwise OR of MRb with MRc.
MARa(31:0) = MARb(31:0) OR MRc(31:0);
This instruction modifies the following flags in the MSTF register:
Flag | TF | ZF | NF | LUF | LVF |
---|---|---|---|---|---|
Modified | No | Yes | Yes | No | No |
The MSTF register flags are modified based on the integer results of the operation.
NF = MRa(31);
ZF = 0;
if(MRa(31:0) == 0) { ZF = 1; }
This is a single-cycle instruction.
