And (AND)
The value at source A is ANDed bit by bit with the value at source B and then
stored in the destination.
Truth Table
Dest = A AND B
A B Dest
0 0 0
1 0 0
0 1 0
1 1 1
Source A and B can either be a word address or a constant; however, both sources
cannot be a constant. The destination must be a word address.
Updates to Arithmetic Status Bits
With this Bit: The Controller:
S:0/0 Carry (C) always resets.
S:0/1 Overflow (V) always resets.
S:0/2 Zero (Z) sets if result is zero; otherwise resets.
S:0/3 Sign (S) sets if most significant bit is set; otherwise resets.
