| uint8_t DMA_CfgDescr_TypeDef::hprot |
HPROT signal state, 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.
