Data Sheet
4.7
The codec provides several test and diagnostic functions which can be grouped as
follows:
• All programmable configuration registers and coefficient RAM-locations are readable
• Digital loop via PCM-register (DLP)
• Digital loop via signal processor (DLS)
• Digital loop via noise shaper (DLN)
• Analog loop via analog front end (ALF)
• Analog loop via converter (ALC)
• Analog loop via noise shaper (ALN)
• Analog loop via Z-sidetone (ALZ); sidetone gain stage GZ must be enabled
(PFCR.GZ = 1) and sidetone gain must be programmed with 0 dB; depending on the
DSSR bit setting in the Data Source Selection Register (DSSR) an addition to the
incoming voice signal is executed.
