MC33591 Technical Data
MOTOROLA
The Header word is a 4 bit Manchester coded message ‘0110’ or its complement sent at the selected data
rate.
This bit sequence and its complement must not be found in the sequence preamble and ID word.
Data must follow the Header without any delay.
Data are completed by a End-of-Message (EOM) word, consisting of 2 NRZ consecutive ones or zeroes.
Even in case of FSK modulation, the data must be completed by a EOM and not by simply stopping the RF
telegram. If the complement of the Header word is received, output data are complemented too.
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 T
Strobe
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) T
Strobe
.
If SOE=0, these timings constraints must be respected by the external control applied on pin STROBE.
