The function of the above three sets of registers are the same. However, they correspond to different THDLC.
A transition from ‘0’ to ‘1’ on this bit indicates an entire HDLC packet is stored in the FIFO and starts the packet transmission.
= 0: Disable the manual abort sequence insertion.
= 1: The abort sequence (‘01111111’) is manually inserted to the current HDLC packet.
This bit is self-cleared after the abortion.
= 0: HDLC mode is selected.
= 1: Reserved.
A transition from ‘0’ to ‘1’ on the this bit resets the corresponding HDLC Transmitter. The reset will clear the FIFO.
