Autosynchronization Completed
12
This bit is set after autosynchronization is complete and when the LASE bit in LINCR1 register is
AUTOSYNC_C
enabled. Only after this bit is set, the contents of LINIBRR and LINFBRR registers should be
OMP
read in autosynchronization mode.
Receive Data Byte Count
RDC contains the number of entries (bytes) in the Receive data buffer in LIN mode.
RDCx is a read-only field available for debug purposes.
