8518.4.2 Short Packet Format
852Figure 11 shows the structure of the Short packet. See sections 8.8 through 8.10 for descriptions of the Data
853Types. A Short packet shall contain an 8-bit Data ID followed by zero to seven bytes and an 8-bit ECC; a
854Packet Footer shall not be present. Short packets can be from two to nine bytes in length.
855The Error Correction Code (ECC) byte allows single-bit errors to be corrected and 2-bit errors to be
856detected in the Short packet.

8598.5 Common Packet Elements
860Long and Short packets have several common elements that are described in this section.
8618.5.1 Data Identifier Byte
862The first byte of any packet is the DI (Data Identifier) byte. Figure 12 shows the composition of the Data
863Identifier (DI) byte.
864DI[7:6]: These two bits identify the data as directed to one of four virtual channels.
865DI[5:0]: These six bits specify the Data Type.
