Functional description
If the input En is set, then the function sets the current level to StSp + Offset "B" for 100 ms.
Then, depending on the connection of Sel, the function runs from the level StSp + Offset "B"
to either level 1 or level 2 at the acceleration set in Rate.
If the input St is set, the function runs to a level of StSp + Offset "B" at the acceleration set in
Rate. Then the function holds the level at StSp + Offset "B" for 100ms. After 100 ms, the level
is set to Offset "B". The scaled value (output AQ) is 0.
If the input St is set, the function can only be restarted after the inputs St and En have been
reset.
If input Sel has been changed, depending on the connection of Sel, the function runs from the
current target level to the new target level at the rate that is specified.
If the input En is reset, the function immediately sets the current level to Offset "B".
The current level is updated every 100 ms. Note the following relationship between output AQ
and the current level:
Output AQ = (current level - Offset "B" ) / Gain "A"
