Receiver Frame Length FIFO (RFLFL/RFLFH):
These are combined to be a 13-bit register. Reading these registers returns received byte count for
the frame. When read, the register of RFLFH will pop-up another frame status and frame length if
FSFDR=1 (Set5.Reg4.Bit7).
Lost Frame Number (LST_NU):
When LST_FR=1 (Set5.Reg4.Bit6), Reg6 stands for LST_NU which is a 8-bit register holding the
number of frames lost in succession.
