DMA_ArbiterConfig_TypeDef DMA_CfgDescr_TypeDef::arbRate

Arbitration rate, ie number of DMA transfers done before rearbitration takes place.

DMA_DataInc_TypeDef DMA_CfgDescr_TypeDef::dstInc

Destination increment size for each DMA transfer

uint8_t DMA_CfgDescr_TypeDef::hprot

HPROT signal state, please refer to reference manual, DMA chapter for further details. Normally set to 0 if protection is not an issue. The following bits are available:

  • bit 0 - HPROT[1] control for source read accesses, privileged/non-privileged access
  • bit 3 - HPROT[1] control for destination write accesses, privileged/non-privileged access
