PinMakes the specified Pin an input.Port.Pin must be a Port.Pin constant declaration.Example : INPUT PortA.0 ‘ Make bit-0 of PortA an inputNotes :An Alternative method for making a particular pin an input is by directlymodifying the TRIS register: -TRISB.0 = 1‘ Set PORTB, bit-0 to an inputThe above method is quicker, and produces less code than the IN-PUT command.All of the pins on a port may be set to inputs by setting the wholeTRIS register at once: -TRISB = %11111111‘ Set all of PORTB to inputsIn the above examples, setting a TRIS bit to 1 makes the pin an input,and conversely, setting the bit to 0 makes the pin an output.70Copyright Crownhill 2001
