CC2642R: How to switch DC-DC mode to LDO mode in active mode?

Hi Team,

The system will never allow a switch to the PWRCTRL_PWRSRC_ULDO when in active mode. This is only allowed when the system is in lower power mode where no code is executing and no peripherals are active.

Customer want to use LDO mode in active mode, How set LDO mode in active mode?
