Port 2

Port 2 is an 8-bit I/O port. Port 2 pins also functions as PWM output pins. Port 2 has a built-in
input pull-up MOS that can be controlled by software. Port 2 has the following registers.

• Port 2 data direction register (P2DDR)

• Port 2 data register (P2DR)
• Port 2 pull-up MOS control register (P2PCR)
8.2.1 Port 2 Data Direction Register (P2DDR)
