7.3.1.2.3 Data Flow into the Mote Serial Port
Figure 10 illustrates the process the mote uses to receive serial data:
The mote may receive serial packets for local commands (not intended for wireless transmission) at any time regardless of the
MT_CTS status.
The mote signals its readiness to receive serial packets for wireless transmission (serial payload command 0x80) by driving
MT_CTS active low. The mote will drive MT_CTS low within interpacket_delay time (see Table 12) after the transmission of
the last packet.

7.3.1.2.4 Timing Values
7.3.2 Mote Command Data Types
Table 13 defines the command data types used in the commands. All values are unsigned.
Table 12 Timing Values
Variable Meaning Min Max Unit
interbyte_delay The time between consecutive data bytes cannot exceed this
time.
0 7 ms
interpacket_delay The sender of an HDLC packet must wait at least this amount
of time before sending another packet.
N/A 20 ms
ack_delay The max time delay between the MT_RTS and the receivers
acknowledge,
SP_CTS.
0 500 ms
time_ack_timeout The mote responds to all TIME pin activation requests within
this time.
N/A 100 ms
diag_ack_timeout The mote responds to all requests within this time. N/A 125 ms
min_strobe_length The length of the strobe signal. 500 ns
boot_delay The time between mote power up and serial interface
availability.
250 ms
