These bits are Low during a read operation.
D5
LOOP
Loop Back Mode Enable. When set to High a loop back mode is enabled where the
output of the sigma delta converter is directly fed to the input of the 1-bit DAC and
where the output of the interpolation filter is fed to the input of the decimation filter.
Receive Channel Clipping. On reading this bit a High indicates an overload condition in
the receive channel.
Transmit Channel Clipping. On reading this bit a High indicates an overload condition in
the transmit channel.
Enable Earpiece. When set to High the earpiece driver is enabled. When set to Low the
earpiece driver is powered down.
Enable Speaker. When set to High the loudspeaker driver is enabled. When set to Low
the loudspeaker driver is powered down. Both drivers may be activated if necessary
e.g. for call progress monitoring.
No Voice. When set to High the voice signal in the receive channel is muted.
