(1) LPDS retention unavailable.
(2) The CC3135MOD modules are compatible with TI BLE modules using an external RF switch.
(3) 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.
