Keypad on P0H

Andrew Jordan

Hi

Since I am using P0H to connect my keypad, I am assuming that I don't require 4 pull-up resistors for 4 lines of columns on P0H0 to P0H3 due to internal pull-up resistors.

Hence four lines of row will be output while inpurs will be on columns. Should I capable of scanning the keypad correctly?

Please let me know asap

Regards

MM
