 Question: 1) How do I handle : 2) What about emulator pins when they are not using the emulator? Answer: Normally output pins are a don't care situation. You can leave these floating if they are not connected to an external device. Input pins (like BSP pins for example) usually do not cause problems. In the case of the BSP, noise can sometimes cause erroneous data to be transmitted or receive. BUT you can put the BSP in reset and keep it there if you are not using it. Control pins which determine the state of the processor should be tied high with a 10K-ohm resistor or less. Pins which need to be low, should be tied to ground directly. |
