Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7-5 | LINK LAYER TESTMODE | R/W | 0h | These bits generate a pattern according to clause 5.3.3.8.2 of the JESD204B document.
000 = Normal ADC data 001 = D21.5 (high-frequency jitter pattern) 010 = K28.5 (mixed-frequency jitter pattern) 011 = Repeat initial lane alignment (generates a K28.5 character and continuously repeats lane alignment sequences) 100 = 12 octet RPAT jitter pattern All others = Not used |
4 | LINK LAYER RPAT | R/W | 0h | This bit changes the running disparity in the modified RPAT pattern test mode (only when the link layer test mode = 100).
0 = Normal operation 1 = Changes disparity |
3 | LMFC MASK RESET | R/W | 0h | Mask LMFC reset coming to digital block.
0 = LMFC reset is not masked 1 = Ignore LMFC reset request |
2-0 | 0 | W | 0h | Must write 0 |
