When high, the FDI PLA and the Filter/Codec are powered down. When low, the FDI is active (default).
When high, the ear driver and Filter/Codec are powered down. In addition, in ST-BUS mode, the selected output
channel is tri-stated. In SSI mode the PCM output code will be -zero code during the valid strobe period. The output will
be tri-stated outside of the valid strobe and for the whole frame if no strobe is supplied. When low, the driver and
Filter/Codec are active if PDFDI is low (default).
When high, a software reset occurs performing the same function as the hardware reset (PWRST) except that the Rst
bit remains high and device remains powered up. A software reset can be removed only by writing this bit low or by
means of a hardware reset (PWRST). This bit is useful for quickly programming the Registers to the default Power
Reset Values. When this bit is low, the reset condition is removed allowing the registers to be modified.
When high the transmit PCM stream is interrupted and replaced with quiet code; thus forcing the output code into a
mute state (only the output code is muted, the transmit microphone and transmit Filter/Codec are still functional). When
low the full transmit path functions normally (default).
mute state. When low the full receive path functions normally (default).
When high, the transmit B2 channel is functional in ST-BUS mode. When low, the transmit B1 channel is functional in
ST-BUS mode. Not used in SSI mode.
When high, the receive B2 channel is functional in ST-BUS mode. When low, the receive B1 channel is functional in
ST-BUS mode. Not used in SSI mode.
