Freezing of the output value
With CURVEC1-HOLD = HIGH the output signals remain the same as of the switching instant
independently of possibly changing input value.
The output are enabled again with CURVEC1-HOLD = LOW. Depending on the function, the output
values change immediately to the now valid input values.
Stop!
They change suddenly!
