E1 ELST Configuration (07CH, 17CH, 27CH, 37CH)
TRKEN:
bits (b7~0, E1-07EH,...) can be set to replace the data or not.
SLIPD:
SLIPE:
E1 ELST Interrupt Indication (07DH, 17DH, 27DH, 37DH)
SLIPI:
E1 ELST Trunk Code (07EH, 17EH, 27EH, 37EH)
TRKCODE[7:0]:
are the trunk codes to replace the received data stream.

In Receive Clock Slave mode and Receive Multiplexed mode, if it is out of synchronization, the trunk code programmed in the TRKCODE[7:0]
= 0: Disable the replacement.
= 1: Enable the replacement.
This bit makes sense only when the SLIPI bit (b0, E1-07DH,...) is ‘1’.
= 0: The latest slip is due to the Elastic Store Buffer being empty.
= 1: The latest slip is due to the Elastic Store Buffer being full.
= 0: Disable the interrupt on the INT pin when the SLIPI bit (b0, E1-07DH,...) is ‘1’.
= 1: Enable the interrupt on the INT pin when the SLIPI bit (b0, E1-07DH,...) is ‘1’.
= 0: No slip occurs.
= 1: A slip occurs.
This bit will be cleared if a ’1’ is written to it.
In Receive Clock Slave mode and Receive Multiplexed mode, if it is out of synchronization and the TRKEN bit (b2, E1-07CH,...) is ‘1’, these bits
