Move/Logical Instructions (MOV, MVM, BTD, MVMT, BTDT, CLR, SWPB, AND, OR, XOR, NOT, BAND, BOR, BXOR, BNOT) Chapter 7
Description: When enabled, the MVMT instruction uses a Mask to either pass or block Source data
bits. A ‘1’ in the mask means the data bit is passed. A ‘0’ in the mask means the data bit
is blocked.
If you mix integer data types, the instruction fills the upper bits of the smaller integer data
types with 0s so that they are the same size as the largest data type.
Enter an Immediate Mask Value by Using an Input Reference
When you enter a mask, the programming software defaults to decimal values. If you
want to enter a mask by using another format, precede the value with the correct prefix.
Arithmetic Status Flags: Arithmetic status flags are affected.
Fault Conditions: None
Execution:
Example: 1. Copy Target into Dest.
