The Level Metering Function is a functional selftest (available per channel), which allows
selftest of the chip (digital, or digital and analogue), and also selftest of the board
(including the SLIC).
An external or internally generated sine-wave signal is fed to the receive path. After
switching a loop (internal or external via the SLIC) to the transmit-path the return level is
measured and compared to a programmable offset value. The result of this operation
(greater or smaller than offset) can be read out via the IOM-2 interface (bit LMR in
configuration register CR2).
There is a single-8-bit Offset-Register available for both two channels. This offset
register can be accessed as XR4 with a XOP-Command (Field LSEL = 100)
This register contains the 2’s complement offset value for the level metering function

and the sensitivity, is available).
