Trying to configure the port pins of P89LPC935. I see there is Open Drain, Push Pull, Quasi Bi, Input Only. Great.
Now i just want to make my pins an output so i set it as Push pull. What is the difference between Port Pin and Port Latch?
Is port pin the physical value i put in software (1 or 0)? If so how does Port latch affects it? For example in Quasi -Bi, it talks about strong and weak pull ups etc depending on levels at the Port Latch and Port Pin.
Can someone clarify this for me or point me to the right information?
Thanks
