3 COMBINE_PCM Combine PCM detection to lock indicator. A 1-bit value to combine the PCM detection
status to the lock indicator. If this bit is logic 0, then the lock indicator does not contain
PCM detection status. If this bit is logic 1, then the PCM detection status is combined
with the lock indicator. Default value 1.
2 BURST_
DET_EN Burst preamble settings. A 1-bit value to enable auto mute when burst preambles are
detected. If this bit is logic 0, then there is no muting. If this bit is logic 1, then there is
muting when preambles are detected. Default value 1.

When writing new settings via the L3-bus or I
2
C-bus interface, these bits should always
remain at logic 0 (default value) to guarantee correct operation.
