(1) LPDS state: The state of unused I/Os is Hi-Z. Software may program the I/Os to be input with pull or drive (regardless of active pin configuration), according to the need.
(2) Hibernate mode: The state of the I/Os is Hi-Z. Software may program the I/Os to be input with pull or drive (regardless of active pin configuration), according to the need.
(3) To minimize leakage in some serial Flash vendors during LPDS, TI recommends that the user application always enables internal weak pulldowns on FLASH_SPI_DIN,
FLASH_SPI_DOUT, and FLASH_SPI_CLK pins.
(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.
(5) For details on proper use, see Drive Strength and Reset States for Analog-Digital Multiplexed Pins.
(6) This pin is one of three that must have a passive pullup or pulldown resistor onboard to configure the chip hardware power-up mode. For this reason, the pin must be output only when
used for digital functions.
(7) This pin is reserved for WLAN antenna selection, controlling an external RF switch that multiplexes the RF pin of the CC3220MODx module between two antennas. These pins must not
be used for other functionalities.
(8) Device firmware automatically enables the digital path during ROM boot.
(9) Requires user configuration to enable the analog switch of the ADC channel. (The switch is off by default.) The digital I/O is always connected and must be made Hi-Z before enabling the
ADC switch.
