12. A: Sample hold B: Inflection point hold
An arbitrary point is held when the SECTION signal is ON. When the Hold Start Level is detected
after turning-ON of the SECTION signal, Inflection Point hold detection starts.
For the Hold Start Level, Detection Start Condition can be selected.
Also, operation can be
performed without using the Hold Start Level with the hold Detection Start Condition External Only.
The value is maintained until the T/H signal turns ON.
13. A: Sample hold B: Relative (Maximum / Minimum / Difference) hold
An arbitrary point is held when the SECTION signal is ON.
When the Hold Start Level is detected after
turning-ON of the SECTION signal, Relative Maximum / Minimum / Difference hold detection starts.
For the Hold Start Level, Detection Start Condition can be selected.
Also, the value is maintained until the T/H signal turns ON with the hold Detection Start
Condition External Only. The value is maintained until the T/H signal turns ON.

If there is no inflection point in the

Also, the H/E signal will not turn ON.
