ORIG mode is a deep sleep mode that can be used for dual mode controller. In this mode, bluetooth controller sleeps between BR/EDR frames and BLE events. A low power clock is used to maintain bluetooth reference clock.

This mode is for BLE only.
EVED mode is for BLE only and is only for internal test. Do not use it for production. this mode is not compatible
with DFS nor light sleep

help
Main crystal can be used as low power clock for bluetooth modem sleep. If this option is selected, bluetooth
modem sleep can work under Dynamic Frequency Scaling(DFS) enabled, but cannot work when light sleep is enabled.
Main crystal has a relatively better performance than other bluetooth low power clock sources.
