Enables the arbiter operation when making an access between DMAC and AHB.
0 should be set to this bit when setting the abtmod and abtpri_* bits of this register.
Please note that 1 cannot be set to this bit in case values set for abtpri_* overlap.
Be sure to set this bit to 1 before starting a DMA access.
