UCC28056: The voltage division ratio of Kzc

XX W
Prodigy 20 points

Part Number: UCC28056

The UCC28056 datasheet and XLS design tool set the Kzc voltage division ratio to 401 by default. Is this the internal default or recommended value of the chip? If my input voltage ranges from 176 to 256 V, can I change this ratio to avoid keeping excessive design margin?
