    How to read port pins in port(P0,x1,x2)?

    temp1 = 1 <<= x1

temp2 = 1 <<= x2
temp2 |= temp1
temp3 = p0
temp3 &= temp2
return (temp3)

    the above describe the needed process maybe not the most elegant way, but that (1 <<= x2) is the only way you can process port pins defined in a function header.

    since you refuse to accept the inability to indirectly address bits, BEFORE YOU POST AGAIN study (I did not say 'read') "the bible" chapter 2. www.8052.com/.../120112
