CHAPTER 9 I/O PORT
9.6
Port 3
Port 3 is a general-purpose I/O port. It can also be used for resource 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 3, lists its
pins, shows a block diagram of the pins, and describes the corresponding registers.
■
Port 3 Configuration
Port 3 consists of the following:
•
General-purpose I/O pins/resource I/O pins (P30/RTO0 to P37/PPG0)
•
Port 3 data register (PDR3)
•
Port 3 data direction register (DDR3)
■
Port 3 Pins
The port 3 I/O pins are also used as resource output pins. Therefore, the pins cannot be used as general-
purpose I/O port pins when they are used as resource I/O pins. Table 9.6-1 lists the port 3 pins.
See "1.7 I/O Circuit Types", for information on the circuit types.
