Port 1

Port 1 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 1 Configuration
Port 1 is made up of the following elements.
• General-purpose I/O pins/peripheral function I/O pins
• Port 1 data register (PDR1)
• Port 1 direction register (DDR1)
• Port 1 pull-up register (PUL1)
• Input level selection register (ILSR)
• Input level selection register (ILSR2)
Port 1 Pins
Port 1 has five I/O pins.
Table 9.3-1 lists the port 1 pins.
