BCLR PORTH,#0; next BCLR PORTH,#1; etc.upto 16 pin.Is it is possible to implement this in a general format (using loop)? Is it is possible BCLR PORTH,# i (but it shows wrong).kindly help me to do this.

Thank you

If you look up the data sheet, you will find that they are memory mapped. Therefore, looping through the correct addresses, you can "read" the status as you wish. This is dependent on the model of course and a special register..

Why are you checking so often? Are you looking for a change? If so, you need to setup an interrupt instead.
