ADDRCTRL - DMA Channel Address Control Register
• Bit [3:2] - ERRINTLVL[1:0]: DMA Channel Error Interrupt Level
These bits enable the interrupt for DMA channel transfer error select the interrupt level as
described in
123. The enabled interrupt will trigger for the conditions when the ERRIF is set.
• Bit [1:0] - TRNINTLVL[1:0]: DMA Channel Transaction Complete Interrupt Level
These bits enable the interrupt for DMA channel transaction complete and select the interrupt
level as described in
on page
• Bit 7:6 - SRCRELOAD[1:0]: DMA Channel Source Address Reload
These bits decide the DMA channel source address reload according to
can not be changed if the channel is busy.
Table 5-4.
• Bit 5:4 - SRCDIR[1:0]: DMA Channel Source Address Mode
These bits decide the DMA channel source address mode according to
can not be changed if the channel is busy.
Table 5-5.
• Bit 3:2 - DESTRELOAD[1:0]: DMA Channel Destination Address Reload
These bits decide the DMA channel destination address reload according to
58. These bits can not be changed if the channel is busy.
