... Controller de-asserts BT_CLK_REQ_OUT_x and internally gates the system clock. This is illustrated in If there is still pending activity at the Bluetooth side on the air, the Bluetooth Controller does not immediately enter Deep Sleep mode and therefore BT_CLK_REQ_OUT_x stays 'active' during this period: however the Bluetooth Controller will go in Deep Sleep mode at the end of the air activity ...

... In the case of an autonomous wake-up with data transmission, the Bluetooth Controller sets BT_SPI_INT high to request the SPI interface and waits for BT_SPI_CSN going low, indicating the SPI transaction starts.
