To request an initial or subsequent PDL, the terminal sends a PARAMETER TYPE of 06 to request an EMV PDL from the host and the TABLE-ID should be 10 to reflect the first Table.

The host will send back a response message containing the Table Versions and Flags:

• A Flag value of "Y" will direct the POS to request the data for that table in a subsequent PDL request.
• A Flag value of "N" indicates that the table is utilized by the location, but there is no new data to download at this time. 
  If the POS needs to download all applicable tables upon new installation or software upgrade, it should process the table as if the Flag value was "Y".
• A Table Version value of "###" and Flag value of "@" will inform the POS that the table is not utilized by the location. If using the "Parameter Data Download system interface partially abstracted" interface, the Flag/Version for the given table will not exist on the response.
• A field that is filled with spaces indicates that it is not applicable to the corresponding Application Identifier (AID).

The POS sends a request for each Table-ID with a Flag value of "Y" using the indicated Table Version and Card Type values. Some of the tables must be downloaded in multiple blocks, and the POS must keep track of the Block Sequence Number it needs and increment it appropriately until all blocks are successfully received. When the POS receives an END-OF-TABLE FLAG of "Y", it sends a PARAMETER TYPE of 07 to confirm receipt of that table.
