The following diagram shows interpacket timing.
Figure 10 Serial Interpacket Timing Diagram
Timout (T1) is the interpacket_delay for communications into the mote, and is defined as the minimum time after the mote
receives the last byte of a packet before it can start receiving the next packet (see
Table 13 for values).
