8.4.3 Data Packets A data packet consists of a PID, a data field containing zero or more bytes of data, and a CRC as shown inFigure 8-7. There are two types of data packets, identified by differing PIDs: DATA0 and DATA1. Twodata packet PIDs are defined to support data toggle synchronization (refer to Section 8.6).

__John So, they are types of data packet, identified by different pid's. But I am still non the wiser. How do they differ? Why make the distinction? What is the significance of each type? Sorry to be a pain
