CHAPTER 9 I/O PORT

Port 6

Port 6 is a general-purpose I/O port. It can also be used for resource input and output.
The port pins can be switched in units of bits between the I/O port and resource. This
section focuses on the general I/O port function. It provides the configuration of port 6,
lists its pins, shows a block diagram of the pins, and describes the corresponding
registers.
■ Port 6 Configuration
Port 6 consists of the following:
• General-purpose I/O pins/resource I/O pins (P60/SIN1 to P63/INT7)
• Port 6 data register (PDR6)
• Port 6 data direction register (DDR6)
■
Port 6 Pins
The port 6 I/O pins are also used as resource I/O pins. The pins cannot be used as general-purpose I/O port
pins when they are used as resource I/O pins. Table 9.9-1 lists the port 6 pins.
