The function of the above three sets of registers are the same. However, they correspond to different THDLC.
This bit is valid in SS7 mode when there is no data in the FIFO to be transmitted.
= 0: Normal operation.
= 1: The 7E (Hex) flags is transmitted N times (the ‘N’ is determined by the FL[1:0] bits (b5~4, E1-0AAH,... / 0ABH,... / 0ACH,...)), then the FISU
A transition from ‘0’ to ‘1’ on this bit indicates an entire HDLC/SS7 packet is stored in the FIFO and starts the packet transmission.
In SS7 mode, when the FIFO is empty and less than 16 bytes are written into the FIFO, these bytes can be transmitted repeatedly with the open-
= 0: Disable the cyclic transmission.
= 1: Enable the cyclic transmission.
= 0: Disable the manual abort sequence insertion.
= 1: The abort sequence (‘01111111’) is manually inserted to the current HDLC/SS7 packet.
This bit is self-cleared after the abortion.
= 0: HDLC mode is selected.
= 1: SS7 mode is selected.
