i was given one assignment with hints, saying that its better not to use more than two outputs at a time. otherwise it might damage the microcontroller.
hi
If you are driving LED's with a series limiting resistor, ensure that when driving the maximum of six LED's that the PIC's total current does not exceed 125mAmps
That means limit the TOTAL LED current plus any other output current to 125mA/6 = 20mA... I would choose 12mA to 15mA per LED
