I have a design using a PSoC4 that has support for bluetooth.
In some cases, we don't need the BLE feature or the external oscillators.
What should be done with the GANT, ANT, and XTAL pins on the packages? Other sources clearly state that unused I/O pins should be configured as outputs and set to one voltage rail or another, but I can't find anything that talks about what should be done with unsued BLE radio pins or XTAL pins.
These unused pins can be left open as long as you don't enable the in your design.
