5.2.3
The Signal Processing Operation Programming (POP) command provides access to the
Enhanced Digital Signal Processor (EDSP) registers of the SLICOFI-2.
Before using an EDSP function the according POP registers have to be programmed.
Any change in any of the POP registers (except registers CIS-DAT and CIS/LEC-MODE)
is only updated with enabling the corresponding device. For example a change of the
center frequency f
UTD-CF-L, switching off the UTD and switching it on again.
The POP registers do no have default values after any kind of reset.
Attention: To ensure proper functionality, the POP registers
5.2.3.1
Please note that the NLP coefficients share the memory location with DTMF and LEC
coefficients. The coefficients are programmed in the following order (Before the first
activation of the EDSP all POP registers have to be programmed. By activation of the
individual functions the contents of the double-used registers are then taken over.):
1. Program the LEC coefficients.
2. Program the DTMF coefficients.
3. Program the NLP coefficients.
Attention: NLP coefficients are only available with SLICOFI-2 Version 1.5
Preliminary Data Sheet
By setting bit LEC-EN in register BCR5 to 1, the coefficients are copied into the EDSP
and the LEC is activated.
By setting bit DTMF-EN in register BCR5 to 1, the coefficients are copied into the
EDSP and the DTMF receiver is activated.
By setting bit NLP-EN in POP register CIS/LEC-Mode to 1, the coefficients are copied
into the EDSP and the NLP is activated. Please note that the NLP can only be
activated, when also the LEC is active.
If the NLP coefficients have been programmed in a prior session, it is possible to
activate the NLP using the old NLP configuration by setting bit NLP-OLDC in POP
register NLP-CTRL to 1.

Furthermore, all unused POP register bits must be filled with zeros.
