Why the condition PDTV="0" needs to be added for the iohgatp.mode check？

//13. DC.iohgatp.MODE encoding is not a valid encoding as determined
​    ​//    by <<IOHGATP_MODE_ENC>>

Thanks for reporting this. The step 13 does not require qualification by PDTV and the code here has an error that is fixed in #449
