can be selected by demasking (register IMR6). Setting both, SILS
and LILS to ´1´ is forbidden.
, automatic switching of remote loop (“on line side”) is disabled
(default).
, automatic switching of remote loop (“on line side”) by In-band loop
codes detected from the line side is enabled if local loop is not
activated by LIM0.LL = ´1´.
, ISR7.XCLKSS1 is enabled.
, ISR7.XCLKSS1 is disabled
, ISR7.XCLKSS0 is enabled.
, ISR7.XCLKSS0 is disabled
