As detailed in ISO/IEC 15693-2, the Configuration Byte (ISO Command Data Byte 0) is an 8-
bit byte that is used to configure the Data Coding Mode and Modulation Depth of the reader.

Bit 4 of the Configuration Byte is used to set Modulation Depth. When set high the
reader is configured for 100% Modulation Depth, when set low the reader will operate
at 10% to 30% (with a 20% nominal setting) Modulation Depth.

Bit 0 of the Configuration Byte is used to set the Data Coding Mode. When set high
the reader is configured for Data Coding Mode 1 / 4; when set low the reader is
configured for Data Coding Mode 1 / 256.

The request packet consists of the header, packet length, node address, command
flags, reader command (60

hex

), ISO/IEC 15693-3 command/data bytes  0 to some

number “n” (where byte 0 is the configuration byte) and the checksum.

The structure of the ISO 15693 Command Data Request is contained within the Data
section of the ISO Command Data, bytes 1 - n.  Specific to the S6350 reader, the ISO
15693 SOF, CRC16 and EOF fields must not be included in the message data packet.
Please refer to ISO/IEC 15693-3 for details about the ISO packet format).  Specific to
the S6350 reader, the ISO 15693 SOF, CRC16 and EOF fields must not be included.

The protocol of S 6350 reader does not use the ISO 15693 SOF,
CRC16 and EOF fields within its message packet.

Please refer to ISO/IEC 15693-3 for details about the ISO message
packet.
