P0.0 to P0.7  
I/O  
Port 0: Port 0 is an 8-bit I/O port with a user-configurable output type. During reset  
Port 0 latches are configured in the input-only mode with the internal pull-up  
disabled. The operation of Port 0 pins as inputs and outputs depends upon the port  
configuration selected. Each port pin is configured independently. Refer to Section  
7.16.1 “Port configurations” and Table 11 “Static characteristics” for details.  
The Keypad Interrupt feature operates with Port 0 pins.  
All pins have Schmitt trigger inputs.  
Port 0 also provides various special functions as described below:  
P0.0 — Port 0 bit 0.
