How do I poll the register of another device?

[dbachman]

The datasheet of the MT8888 DTMF transceiver says to read the status register and if bit one is set, do the next step. The datasheet says to send b7, b6 and b5 as %110. Do I make portb = %11000000? On the next statement do I say "If portb.1 = 1 then next step"? I'm kind of stuck and any enlightenment would sure help.

Thanks, Don

While thinking about it more, Can I send %11000000 on portb, then "Trisb = $1111111" then do the If Then statement to check if b1 is set?
