Port 2
Port 2 is an output-only port.
The section describes the port structure and pins, the pin block diagram, and the port
registers for port 2.
Structure of Port 2
Port 2 consists of the following two components:
•
Output-only pins (P20 to P27)
•
Port 2 data register (PDR2)
Port 2 Pins
Port 2 consists of eight output pins of a CMOS output type.
Table 4.4-1 lists the port 2 pins.
