---|---|---|---|---|
Reserved | 31:26 | roRead-only | 0x0 | Reserved. Return zeros on reads. |
ZDATA_PU_ODT_RESULT | 25:16 | roRead-only | 0x0 | Pullup termination calibration code result: Data value as a result of calibration or VT updates or can be used to directly drive the impedance control. The calibration result is updated either after the first calibration completes or when a VT drift related update is performed. |
Reserved | 15:10 | roRead-only | 0x0 | Reserved. Return zeros on reads. |
ZDATA_PD_ODT_RESULT | 9:0 | roRead-only | 0x0 | Pulldown termination calibration code result: Data value as a result of calibration or VT updates or can be used to directly drive the impedance control. The calibration result is updated either after the first calibration completes or when a VT drift related update is performed. |
