Logical Instructions (Accumulator)
And (AND logical)
The AND instruction is a 16-bit instruction that logically ANDs
the value in the lower 16 bits of the accumulator with a specified
V-memory location (Aaaa). The result resides in the accumulator.
The discrete status flag indicates if the result of the AND is zero.
NOTE: Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the value in V2000 will be loaded into the accumulator
using the LD instruction. The value in the accumulator is ANDed with the value in V2006
using the AND instruction. The value in the lower 16 bits of the accumulator is output to
V2010 using the OUT instruction.
