Other Parts Discussed in Thread: CC3220SF
In the CC3220SF_LAUNCHXL.c we can define the Paking state of GPIO during LPDS:
/*
* =============================== Power ===============================
*/
/*
* This table defines the parking state to be set for each parkable pin
* during LPDS. (Device pins must be parked during LPDS to achieve maximum
* power savings.) If the pin should be left unparked, specify the state
* PowerCC32XX_DONT_PARK. For example, for a UART TX pin, the device
* will automatically park the pin in a high state during transition to LPDS,
* so the Power Manager does not need to explictly park the pin. So the
* corresponding entries in this table should indicate PowerCC32XX_DONT_PARK.

Where I can find the detailed explanation of this feature in the manuals?
I tried to search "park" in the following documents with no results:
- SWAS035A
- SWRU465
- SWRU455C
