Field Documentation

◆ txDllLowWindowStart

int32_t OSPI_PhyTuneWindowParams::txDllLowWindowStart

Tx Dll window lower value to search RxDLL low and high. This corresponds to the bottom left point serach.

◆ txDllLowWindowEnd

int32_t OSPI_PhyTuneWindowParams::txDllLowWindowEnd

Tx Dll window higher value to search RxDLL low and high. This corresponds to the bottom left point search.

◆ txDllHighWindowStart

int32_t OSPI_PhyTuneWindowParams::txDllHighWindowStart

Tx Dll window lower value to search RxDLL low and high. This corresponds to the top right point search.

◆ txDllHighWindowEnd

int32_t OSPI_PhyTuneWindowParams::txDllHighWindowEnd

Tx Dll window higher value to search RxDLL low and high. This corresponds to the top right point search.

◆ rxLowSearchStart

int32_t OSPI_PhyTuneWindowParams::rxLowSearchStart

Rx Dll lower value for Rx Dll low search. The value of Rx dll will lie in this window bottom left point search.

◆ rxLowSearchEnd

int32_t OSPI_PhyTuneWindowParams::rxLowSearchEnd
