Bit | Field | Type | Reset | Description |
---|---|---|---|---|
15:8 | LANE_ENA | 0x00 | Turn on each lane as needed. Signal is active high.
bit 15 : lane7 enable bit 14 : lane6 enable bit 13 : lane5 enable bit 12 : lane4 enable bit 11 : lane3 enable bit 10 : lane2 enable bit 9 : lane1 enable bit 8 : lane0 enable |

7:6 | JESD_TEST_SEQ | 00 | Set to select and verify link layer test sequences. The error for these sequences comes out the lane alarms bit0. 1= a fail and 0 = pass.
00 : test sequence disabled 01 : verify repeating D.21.5 high frequency pattern for random jitter 10 : verify repeating K.28.5 mixed frequency pattern for deterministic jitter 11 : verify repeating ILA sequence |

1:0 | JESD_PHASE_MODE | 11 | Used to tell the JESD block how many clock phases are being used for lanes.
00 = 1 phase 01 = 2 phases 10 = 4 phases 11 = 8 phases |
