I am using KDS v3.2 with Processor expert on a MK22FN256LVH12 on a Custom board.
I am currently using a Bluetooth chip connected to the UART2 of chip, and I've noticed that even when I turn the bluetooth chip off, and turn the reset low (resetting it) that my UART lines remain at 3.3V. This is even when I set the microcontroller to VLSS1 to sleep.
I've tried setting the UART pins to pulldown, pullup, open drain, no open drain, basically anything to see if the pin settings will stop it from being awake. Any suggestions or thoughts would be appreciated!
