Logical-OR for bit variables
Set the carry flag if the Boolean value is a logical 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:
