This command is deprecated. Do not use it in new code as we may remove it in the future!

This commands prepares the reader to access ISO15693 cards with the given settings. It can be called before using VHL.Read and VHL.Write with ISO15693 cards without configuring the reader with a VHL-file, i.e. when the ID parameter of VHL.Read or VHL.Write is set to 0xFF.

After calling VHL.Select, VHL.Read or VHL.Write with an ID parameter other than 0xFF, or after a reboot, the settings made by this command are lost. Firmware versions 1100 2.07.00 and above also support 16-bit length values for the FirstBlock and BlockCount parameters. This is not explicitly documented. For new applications, the command VHL.Setup should be used instead.
