2. BSYNC_GAIN. Changes to this bit take effect immediately.

4. Changes to this bit take effect immediately.
5. HOP_ENABLE. Changes to this bit take effect immediately.
6. SLEEP_WAKE. This bit must be set to enable the core to put itself to sleep via the GO_TO_SLEEP command. The SLEEP_WAKE
7. SYNC_AQC_CLEAR. This bit must be set to “1” again after every “clear” operation to allow for the next “clear”.
8. FRAME_START_CLEAR. This bit must be set to “1” again after every “clear” operation to allow for the next ?“clear”.
this bit is set to 0, the ADPCM Processor clock restarts within two clock periods; in every case, the ADPCM Processor clock min-
imum specifications for high time and low time are respected.
BIAS_ENABLE. This bit is a global enable for the Automatic Frequency Control. When the bit is set, the AFC hardware updates
the current BIAS_ERROR_DATA during specific time windows, controlled by the event trigger hardware and suitable for a good
operation of the AFC. When the bit is reset, the AFC operation is suspended. However, the current BIAS_ERROR_DATA, result-
ing from previous bias estimations, can still be used to bias the downconverter NCO. Changes to the BIAS_ENABLE bit take effect
at the beginning of the frame following the change.
register fields) and power to the modulator and NCO (timing set by MOD_PWR_ON and the wake/sleep modes).
bit must be reset to prevent the core to fall back to sleep after it is awaken by one of the Port 0 Wake-up pins when the sleep period
has not expired. If the bit is not reset, the core will fall right back to sleep when the wake-up input is de-asserted (note that by
design, a wake-up input has a minimum of 10 ms duration, to allow the software enough time to safely reset the SLEEP_WAKE
bit).
