H0-INF 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 terminals are connected via 
network, use the MCU 5000A on this setting.
STEP PROCEDURE 
Note:
If the physical line number is set with any value from “01H” to “10H”, the line will be fixed 
as the clock source.  In this case, care must be taken because an abnormal state of the line 
would lose the clock source and also cause the other lines to lose synchronization.  If the MCU 
5000A is connected to some terminals directly and to others via network, be sure to use the 
line connected via network as the clock source.  When set to “internal”, the intra-MCU crystal 
oscillator clock will supply the line clock.  If MCU 5000A must be connected directly to all 
the terminals without going through network, use the MCU 5000A with this “internal” setting 
on.
