= 0: Disable the interrupt on the INT pin when the BERI bit (b3, E1-073H,...) is ‘1’.
= 1: Enable the interrupt on the INT pin when the BERI bit (b3, E1-073H,...) is ‘1’.
= 0: No bit error is inserted to the generated pattern.
= 1: A single bit error is inserted to the generated pattern.
This bit is cleared after the single bit error insertion is completed.
= 0: The pattern is out of synchronization (the pattern detector has detected 10 or more bit errors in a fixed 48-bit window).
= 1: The pattern is in synchronization (the pattern detector has detected at least 48 consecutive error-free bit periods).
= 0: Disable the interrupt on the INT pin when the SYNCI bit (b0, E1-073H,...) is ‘1’.
= 1: Enable the interrupt on the INT pin when the SYNCI bit (b0, E1-073H,...) is ‘1’.
= 0: No bit is mismatched with the PRGD pattern when the extracted data is in synchronization state.
= 1: At least one bit is mismatched with the PRGD pattern when the extracted data is in synchronization state.
This bit will be cleared if a ’1’ is written to it.
= 0: There is no status change on the SYNCV bit (b1, E1-072H,...).
= 1: There is a transition (from ‘0’ to ‘1’ or from ‘1’ to ‘0’) on the SYNCV bit (b1, E1-072H,...).
This bit will be cleared if a ’1’ is written to it.
