Hello. Does someone knows if the current limit for non special ports (like led drivers or high current sink) are the ones specified below? These were copied from the MC68HC908JB16 datasheet.
Output high voltage (ILoad = –2.0 mA)
PTA0–PTA7, PTC0–PTC1, PTE0–PTE2
Output low voltage(ILoad = 1.6 mA) All I/O pins
(ILoad = 25 mA) PTD0–PTD1 in ILDD mode(ILoad = 10 mA) PTE3–PTE4 with USB is disabled
Is it correcto to say that a non special port can have a 1.6mA sink current at maximum and consequently it has to be connected to a pull-up resistor (for open-drain configuration) with a value higher than 3125 Ohms (VCC=5V)?
If the port specification don't specify a port is open drain as output, what other thing (electrically) can it be and how can I represent it whit equivalent components for simulation?
