Figure 33: Typical Data Frame
Bit 1 is the first serial bit to be received. When enabled, the primary, secondary
and universal addresses are compared with the high order packet address to
determine a match.
Figure 34: Example Multi-Packet Operational Sequence
Figure 34 shows the timing of interrupts, the state of the FIFO, and the state of
the Data Link relative the input data sequence. The cause of each interrupt and
