Port 0

Port 0 is a general-purpose I/O port.
This section focuses on functions as a general-purpose I/O port.
See the chapters on each peripheral function for details about peripheral functions.
Port 0 Configuration
Port 0 is made up of the following elements.
• General-purpose I/O pins/peripheral function I/O pins
• Port 0 data register (PDR0)
• Port 0 direction register (DDR0)
• Port 0 pull-up register(PUL0)
• A/D input disable register low order(AIDRL)
• Input level selection register (ILSR2)
Port 0 Pins
Port 0 has eight I/O pins.
Table 9.2-1 lists the port 0 pins.
