 CSV has many of the same subtleties in usage as CLTV:
 
 * The `nVersion` field must be set to 2 or more.
-* The `nSequence` field must be set to less than 0xf0000000.
+* The `nSequence` field must be set to less than 0x80000000.

 * The `nSequence` must be greater than or equal to the stack operand.
