CFS ... Configuration Select
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
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 microcontroller can enforce the "Power Up" state
and with C/I command Deactivation Indication (DI) 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.
1: The IOM interface clock and frame signals are normally inactive ("Power Down").
For activating the IOM-2 clocks the "Power Up" state can be induced by software
(IOM_CR.SPU) or by resetting CFS again.
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 (DI).
Note: After reset the IOM interface is always active. To reach the "Power Down" state

generated at RSTO.
After the selection of the watchdog timer (RSS = ’11’) the timer is reset and started.
During every time period of 128 ms the microcontroller has to program the WTC1 and
WTC2 bits in two consecutive bit pattern (see description of the WTC1, 2 bits)
the CFS-bit has to be set.
