State of USB pins during Power on Reset (POR) in PSoC 3/5
What is the Power on Reset (POR) state of USB pins in PSoC 3/5?
When an USB component is used in the project, it uses the USB pins 15 and 15. PSoC Creator internally assigns the POR state of “High-Z Analog” to these USB pins. So, if some pins on the project schematic are assigned to other PORT 15 pins, they must also have the POR state of “High-Z Analog”. PSoC 3/5 requires all pins of a physical port to have the same POR state, otherwise error will be generated during project build operation.
The POR state of a pin can be changed on the schematic, by configuring the Reset tab in the pin component configuration.
