The following example shows a complete message with Preamble, ID, Header words followed by 2 data bits,
and an EOM. The preamble is placed at the beginning of both ID and Header words.
Figure 5: Complete message example
MESSAGE PROTOCOL
If the receiver is continuously Sleep/Run cycling, the ID word has to be recognized to stay in Run mode.
Consequently, the transmitted ID burst has to be long enough to include two consecutive receiver Run cycles.
If the Strobe oscillator is enabled (SOE=1), the circuit is in Sleep mode during SR

and in Run mode
during T
Strobe
(where T
Strobe
is the Strobe oscillator period and SR is the Strobe Ratio, see Table 5). Therefore,
the sleep/run cycle period is equal to (SR+1)

.
If SOE=0, these timings constraints must be respected by the external control applied on pin STROBE.
