CTAB with periodic curve tables
If the specified <master value> is outside the definition range, the master value is evaluated
modulo of the definition range and the corresponding following value is output:
Approximate value for CTABINV
The CTABINV command, therefore, requires an approximate value for the expected master
value. CTABINV returns the leading value that is closest to the approximate value. The
approximate value can be, for example, the master value from the previous interpolator clock
cycle.
