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, T1/J1-07DH) 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, T1/J1-07DH) is ‘1’.
= 1: Enable the interrupt on the INT pin when the SLIPI bit (b0, T1/J1-07DH) 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, T1/J1-07CH) is ‘1’, these bits
