|---|---|---|---|---|
| 7 | RESERVED | R/W | 0 | RESERVED |
| 6 | SYSREF_PROC_EN | R/W | 0 | This bit enables the SYSREF processor. This bit must be set to allow the device to process SYSREF events. SYSREF_RECV_EN must be set before setting SYSREF_PROC_EN. |
| 5 | SYSREF_RECV_EN | R/W | 0 | Set this bit to enable the SYSREF receiver circuit. |
| 4 | SYSREF_ZOOM | R/W | 0 | Set this bit to zoom in the SYSREF strobe status (affects SYSREF_POS). |
| 3-0 | SYSREF_SEL | R/W | 0000 | Set this field to select which SYSREF delay to use. Set this field based on the results returned by SYSREF_POS. Set this field to 0 to use SYSREF calibration. |
