beacon-Enabled (Coordinator or Device) mode. In this
processor with a wake-up alert interrupt (0x31<6>).
Nonbeacon-Enabled (Coordinator or Device) mode –
Figure 3-19 shows the Sleep time line for Non-
mode, the host processor puts the MRF24J40 to Sleep
by setting the STARTCNT (0x229<7>) bit. At the end of
the Sleep interval, the MRF24J40 alerts the host
