Logical-AND for bit variables
If the boolean value of the source bit is a logical 0 then clear the carry flag;
otherwise leave the carry flag in its current state. A slash (“/”) preceding the
operand in the assembly language indicates that the logical complement of the
addressed bit is used as the source value, but the source bit itself is not
affected. No other flags are affected.
Only direct addressing is allowed for the source operand.
Set the carry flag if, and only if, P1.0 = 1, ACC. 7 = 1, and OV = 0:
