The function of the above three sets of registers are the same. However, they correspond to different THDLC.
When the FIFO is empty and the last transmitted byte is not the end of the current HDLC packet, the under-run occurs. This bit indicates whether
= 0: No under-run occurs.
= 1: Under-run occurs.
This bit will be cleared if a ’1’ is written to it.
= 0: There is no status change on the RDY bit (b0, T1/J1-0B0H,... / 0B1H,... / 0B2H,...).
= 1: There is a transition (from ‘0’ to ‘1’) on the RDY bit (b0, T1/J1-0B0H,... / 0B1H,... / 0B2H,...).
This bit will be cleared if a ’1’ is written to it.
