If enabled by bit FMR5.XLD the LLB deactuate code will automatically
repeat until the LLB generator is stopped. Transmit data is overwritten
by the LLB code. LDC0 is transmittted last. For correct operations bit
LCR1.XPRBS has to cleared.
If enabled by bit FMR5.XLU the LLB actuate code will automatically
repeat until the LLB generator is stopped. Transmit data is overwritten
by the LLB code. LAC0 is transmittted last. For correct operations bit
LCR1.XPRBS has to cleared.
