The function of the above three sets of registers are the same. However, they correspond to different RHDLC.
The overwritten condition will occur if data is still attempted to write into the FIFO when the FIFO has already been full (128 bytes).
= 0: No overwriting occurs.
= 1: The overwriting occurs.
This bit will be cleared if a ’1’ is written to it.
= 0: No block is pushed into the FIFO.
= 1: A block of the HDLC packet is pushed into the FIFO.
This bit will be cleared if a ’1’ is written to it.
