You have built a circuit to connect an LED between a PIC16F877 port pin and ground (via a resistor). You have written a program which toggles the port pin which the LED is connected to. When you run the program on the PIC16F877, the LED does not appear to flash. Which ONE of the following statements is NOT a plausible explanation?

Question

Accepted Answer

The port pin cannot sink sufficient current to light the LED

Answer

The port pin was configured as in input

Answer

The port pin is faulty

Answer

The port pin has open-drain output circuitry, and cannot exert a "true" high value

Answer

The LED is faulty or is connected backwards
