Receiver
If a valid preamble pattern or start frame delimiter is detected, the receiver continues decoding
with the same synchronization. If the stream does not match a valid preamble pattern or a start
frame delimiter, the receiver re-synchronizes at the next valid edge. When a valid start sequence
has been detected, the decoded data is passed to the USART and the user will be notified of
any incoming Manchester encoding violations by the Manchester Error bit (CSR.MANE). This bit
is cleared by writing a one to the Reset Status bits in the Control Register (CR.RSTSTA). A vio-
lation occours when there is no transition in the middle of a bit period. See
illustration of a violation causing the Manchester Error bit to be set.
Figure 25-15. Manchester Error
This section describes low data rate, full duplex, dual frequency, RF systems integrated with a
Manchester endec, that support ASK and/or FSK modulation schemes. See
To transmit downstream, encoded data is sent serially to the RF modulator and then through
space to the RF receiver. To receive, another frequency carrier is used and the RF demodulator
