A5.12 External-output Tracking (LO)
Externaltrackingistheactionofoutputtingthesetvalueoftheoperationoutput(TRK_VAL).
External tracking functions when the block mode is LO.

To change the block mode to LO:
Set Track Enable in CONTROL_OPTS.
IfTRK_IN_Dissettotrue,theblockmodebecomesLO.
However, to change the block mode from Man to LO, both Track Enable and Track in Manual
mustalsobespeciedinCONTROL_OPTS.
