Field Documentation

bufLowThreshold

uint32_t CSL_DssWbPipeDmaCfg::bufLowThreshold

Write back DMA buffer low threshold. Number of 128 bits defining the threshold value

bufHighThreshold

uint32_t CSL_DssWbPipeDmaCfg::bufHighThreshold

Write back DMA buffer high threshold. Number of 128 bits defining the Threshold value

arbitration

uint32_t CSL_DssWbPipeDmaCfg::arbitration

Determines the priority of the write back pipeline. For valid values see CSL_DssWbPipePriorityVal

frameCaptureRate

uint32_t CSL_DssWbPipeDmaCfg::frameCaptureRate

Frame capture rate of the write back pipeline. For valid values see CSL_DssWbPipeCaptRate

idleSize

uint32_t CSL_DssWbPipeDmaCfg::idleSize

Determines if idleNumber corresponds to number of bursts or singles. Possible values are 0 or 1

idleNumber

uint32_t CSL_DssWbPipeDmaCfg::idleNumber

Determines the number of idles between requests on the L3 interconnect. Used only in memory to memory mode. Range depends on idleSize parameter Range: 0-15 when idleSize is 0 0-120 when idleSize is 1
