(1) LPDS retention unavailable.
(2) Pin 45 is used by an internal DC/DC (ANA2_DCDC). For CC3235S device, pin 45 can be used as GPIO_31 if a supply is provided on pin 47.
(3) Future support.
(4) 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.
