1.5M LIF CLOCK SOURCE SETTING
LINE RELATED
SUMMARY:
Specifies the line from which to extract the line clock to be used inside the MCU 
5000A.  When set to “auto”, the line whose line signal is the first to turn normal 
will be specified as the clock source, but it will be replaced by the lowest-
numbered line currently in normal operation once the line acting as the clock 
source then ceases being normal.  When all the...
