Sleep (SL) – only available with DuSLIC-E/-E2/-P/-ES/-ES2
The SLICOFI-2 is able to go into Sleep mode with minimal power dissipation. In this
mode, off-hook detection is performed without any checks on spikes or glitches. The
Sleep mode can be used for either channel, but for the most effective power savings,
both channels should be set to this mode. Note that this requires the following:

Preliminary Data Sheet
CIOP = Command/Indication Operation
For further information, see
If both channels are set to the Sleep mode, only non-noisy lines should be used due
to the lack of persistence checking. Wake up takes about 1.25 ms, as the on-chip
PLL is also switched off. Therefore, it is also possible to switch off all external clocks.
In this mode, no programming or other functionality is available. The off-hook event
is indicated either by (1) setting the interrupt pin to Low level, if the PCM/ C Interface
mode is selected, or (2) pulling down the DU pin, if IOM-2 Interface is used.
If only one channel is set to Sleep mode, persistence checking and off-hook
indication are performed as in any other mode, but the off-hook level is fixed to 2 mA
at the subscriber line. No special wake up is needed if only one channel is in Sleep
mode. A simple mode change ends the Sleep mode.
A sleeping SLICOFI-2 wakes up if the CS pin is drawn to low level when the PCM/ C
Interface is used or if the MX bit is set to 0 when the IOM-2 Interface is used. Note
