Port 2 Output Data Status Bit
0 = The real level of corresponding pin is at logic 0.
1 = The real level of corresponding pin is at logic 1.
Values read from the address of this register reflect the external state of port 2 not the value
written to this register. Even though the port is configured as a functional pin except ADC, user
can know the external state of port 2 by reading this register.
