Note: PTA is an enhanced feature for co-existence of the WINCS02 Module with Bluetooth® devices. For more details, refer to the WINCS02 Family Data Sheet (DS70005577). Pin 11 of the module is Reserved on the WINCS02 Module. The recommendation is to connect this pin with a tri-state pin on the host board/application board for future use. While using the PTA feature, the user cannot use the RTCC oscillator functionality. For more details, refer to the WINCS02 Software Release Notes. If VDD and VDDIO are connected within the 3.0-3.6V voltage range
