Once all the functional chirps are transmitted, the rl_fecssDevClockCtrl API can be used to power-off the APLL while entering deep sleep. The rl_fecssDevPwrOff API can be used for power down the FECSS. FECSS power down must be done with retaining the memory.
After successfully entering deep sleep and while exiting deep sleep, the rl_fecssDevPwrOn can be used to power up the FECSS. FECSS powerup must be done in warm boot mode. The configuration structure of the rl_fecssDevClockCtrl API has a sub field, c_ApllClkCtrl, that can be used to powerup the APLL. APLL hardware calibration is not needed during the warm boot or after exiting deep sleep.
