I'm going through the 'Electrical Characteristics' section of datasheet of PIC24EP128GP206 to find out minimum and maximum voltages and currents specific to GPIO pins.
While doing so, I came across the terms IOL, IOH in the following section:
What do the IOL, IOH currents exactly represent? Are these the sourcing / sinking currents associated with the output pins? Why is the IOH limit is mentioned negative?
