The number of read is placed in the IO0Pin register. IO0PIN& (1<<7) just determines whether the corresponding bit is 1; if (IO0PIN&pin0) i|= (1<<7) is 0, of course, and I is the new byte formed by those final input combinations. PS: sorry, last time you forgot to add parentheses, 1<<7 must add parentheses.
