8.3
8.3.1
The closing Flag of a previously transmitted frame simultaneously becomes the opening
Flag of the following frame if there is one to be transmitted. The Shared Flag feature is
enabled by setting bit SFLG in control register CCR1.
8.3.2
If enabled via register CCR3, a programmable 8-bit pattern (defined by register PRE) is
transmitted with a selectable number of repetitions after Interframe Timefill transmission
is stopped and a new frame is ready to be sent.
Zero bit insertion is disabled during preamble transmission. To guarantee correct
function the programmed preamble value should be different to the Receive Address
Byte values. Otherwise the preamble could be detected as valid address with shared
flags.
In BOM mode the MSB of the preamble should be reset in order to achieve a faster
synchronization at the BOM receiver. After the preamble has been sent, the transmitter
inserts one sync byte (FF

Received data is always shifted into RFIFO.
Data transmission is always performed out of XFIFO by shifting the contents of XFIFO
directly into the outgoing data stream. Transmission is initiated by setting CMDR.XTF. A
