9.6.1. Formatter data processing

Figure 9.13 shows the arrangement of four words and organization of the data packets.

When a trace source is changed the appropriate flag bit, F, is set (1 = ID, 0 = Data on the first byte). The second byte is always data. The corresponding bit at the end of the sequence (bits A to J) indicates if this second byte corresponds to the new ID (bit clear) or the previous ID (bit set).
