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. ORIG mode is a bluetooth sleep mode that can be used for dual mode controller. In this mode,

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
