This bit determines clock relations and recovery on S/T and IOM interfaces.
0: The IOM interface clock and frame signals are always active, "Power-Down" state

Layer 2 transmits IOM channel 0 and 2 on IDP1, channel 1 on IDP0.
Layer 2 transmits IOM channel 0, 1 and 2 on IDP1.
included.
The states "Power-Down" and "Power-Up" are thus functionally identical except
for the indication: PD = 1111 and PU = 0111.
With the C/I-command Timing (TIM) the processor can enforce the "Power-Up"
state.
With C/I-command Deactivation Indication (DIU) the "Power-Down" state is
reached again.
However, it is also possible to activate the S-interface directly with the
C/I-command Activate Request (AR 8/10/L) without the TIM command.
For activating the S interface the "Power-Up" state can be induced by software
(SPU bit in SPCR register).
After that the S interface can be activated with the C/I-command Activate
Request (AR 8/10/L).
The "Power-Down" state can be reached again with the C/I command-
Deactivation Indication (DIU).
After reset the IOM interface is always active. To reach the "Power-Down" state
the CFS bit has to be set.
