◆ Cy_AXIDMAC_Descriptor_SetDescriptorType()

void Cy_AXIDMAC_Descriptor_SetDescriptorType ( cy_stc_axidmac_descriptor_t *  descriptor,
cy_en_axidmac_descriptor_type_t  descriptorType 
)

Sets the descriptor's type for the specified descriptor.

Moves the next descriptor pointer and M data count values into the proper offset in accordance to the actual descriptor type.

During the descriptor's type change, carefully set up the settings starting from dstAddress and all the rest below in the cy_stc_axidmac_descriptor_config_t structure. This is because the content of the descriptor registers might be lost/overridden by other descriptor settings due to the different registers structure for different descriptor types.
