Figure 33. Fixed Length Packet Format
Variable Length Packet Format
Variable length packet format is selected when bit PacketFormat is set to 1.
This mode is useful in applications where the length of the packet is not known in advance and can vary over time. It is then
necessary for the transmitter to send the length information together with each packet in order for the receiver to operate
properly.
In this mode the length of the payload, indicated by the length byte, is given by the first byte of the FIFO and is limited to
255 bytes. Note that the length byte itself is not included in its calculation. In this mode, the payload must contain at least 2
bytes, i.e. length + address or message byte.
An illustration of a variable length packet is shown below. It contains the following fields:
Preamble (1010...)
Sync word (Network ID)
Length byte
Optional Address byte (Node ID)
Message data
