A transition from ‘0’ to ‘1’ on this bit resets the corresponding HDLC Receiver. The reset will clear the FIFO, the PACK bit (b0, T1/J1-095H,... /
The function of the above three sets of registers are the same. However, they correspond to different RHDLC.
= 0: All valid HDLC/SS7 blocks are pushed into the FIFO.
= 1: The FIFO is empty, i.e., all the blocks are read from the FIFO.
The corresponding HDLC Receiver reset will clear this bit.
= 0: The byte read from the FIFO is not an overhead byte.
= 1: The byte read from the FIFO is an overhead byte.
The corresponding HDLC Receiver reset will clear this bit.
