7.1
This function allows a selftest of the SICOFI-4 and also of the SLIC circuitry connected
to the analog interface.
The receive path has to be stimulated with a sine wave applied to the digital input, or
generated by one of the internal tone generators. By closing an internal or external (via
the SLIC) loop to the transmit path, the outgoing signal is compared with a
programmable offset.
(For further information, an application-note describing the calculation of the offset value
and the sensitivity, is available)
