TE may not enter the basic setting mode. In this case it is necessary to reset the
SICOFI2/4-TE or to initialize the SICOFI2/4-TE configuration registers to ‘0’.
The SICOFI2/4-TE leaves this mode automatically after the RESET-pin is released.
3.6.2
After releasing the RESET-pin, (RESET-state), the SICOFI2/4-TE will enter the Standby
mode. The SICOFI2/4-TE is forced to standby mode with the PU-bit set to ‘0’ in the
CR1-register (POWERDOWN). All 2/4 channels must be programmed separately.
During standby mode the serial SICOFI2/4-TE -Controller interface is ready to receive
and transmit commands and data. Received voice data on DU, DD-pin will be ignored.
SICOFI2/4-TE configuration registers and Coefficient-RAM can be loaded and read back
in this mode. Data on signaling input pins can be read via the -Controller interface.

3.6.3
The operating mode for any of the four channels is entered upon recognition of a PU-bit
set to ‘1’ in a CR1-register for the specific channel.
3.6.4
Based on an advanced digital filter concept, the SICOFI-2/4 TE provides excellent
transmission performance and high flexibility. The new filter concept leads to a maximum
independence between the different filter blocks.
