(1) LPDS retention is unavailable.

(2) The CC3235MODx or CC3235MODAx modules are compatible with TI BLE modules using an external RF switch.

(3) Future support.

(4) This pin is not accessible on the CC3235MODAx devices as it is directly tied to the integrated antenna.

(5) This pin has dual functions: as a SOP[2] (device operation mode), and as an external TCXO enable. As a TXCO enable, the pin is an output on power up and driven logic high. During hibernate low-power mode, the pin is in a Hi-Z state but is pulled down for SOP mode to disable TCXO. Because of the SOP functionality, the pin must be used as an output only.
