Logical OR for bit variables
Set the carry flag if the Boolean value is a logic 1; leave the carry in its current state
otherwise. 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.
Set the carry flag if, and only if, P1.0 = 1, ACC.7 = 1, or OV = 0:
