causes a special behaviour if a link error occurs. The remainder of the last written packet remains in the internal pipe which
is not cleared in case of a SpaceWire link error. After the link reconnects, this remainder will be transmitted immediately
after a new data character or an EOP is written to the HOCI FIFO.
To prevent a transmission of the remaining bytes in front of a new packet after link reconnects, following sequence is
proposed:
1. After the link disconnects, reset the transmit section of the channel by setting of bit D0 in register CHx_CNTRL2
2. If the packet isn't finished with an EOP then close the packet by writing to the EOP register 0x27 (transmit EOP)
3. Clear the bit D0 in register CHx_CNTRL2
4. restart the link
