The 73M1x66B operates normally.
In this mode the Host Side of the Barrier interface is disabled and the
line side device is disabled. The Host side continues to operate
normally.
The device PLL is turned off and PCLK is propagated on the clock
tree. The PCM DX and TSC outputs are tri-stated. Control and status
registers of the Host side maintain their content.
The device is shut down altogether. The registers remain accessible
through the SPI. Control and status registers of the Host side maintain
their content. To restart the PCM operations, the PCODE register
must be set for the appropriate PCLK frequency value.

Enable Front End Host
1 = Enable Front End of the 73M1906B Host-Side Device. (Default)
0 = Disable Front End of the 73M1906B Host-Side Device.
Power Down Mode
0 = Disable Power Down Mode. (Default)
1 = Enable Power Down Mode.
Sleep Mode
0 = Disable Sleep Mode. (Default)
1 = Enable Sleep Mode.
Force VCO
0 = The system clock is the same as PCLK. (Default)
1 = The system clock is derived from locked PLL. This is set to 0
upon reset, Sleep or Power Down mode enabled.
Phase Locked Loop Lock Detect
0 = PLL is not locked. (Default)
1 = PLL is locked to PCLK.
