Power Management
The 73M1x66B supports three modes of power control for the device.
Normal mode
The 73M1x66B operates normally.
ENFEH = 0
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.
Sleep mode
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.
Power Down
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.
In all reduced power modes of operation the SPI interface remains active.
