The receiver is normally configured until a message is detected. 1 TDE Transmitter DMA Enable Setting this bit allows transmit DMA requests to the DMA controller. Fro transmit DMA operation, this bit must be set and a DMA channel must be enabled to utilize the request. 0 Transmit DMA disabled 1 Transmit DMA enabled 0 RDE Receiver DMA Enable Setting this bit allows received DMA requests to the DMA controller. For receive DMA operation, this bit must be set and a DMA channel must be enabled to utilize the request. 0 Receive DMA disabled 1 Receive DMA enabled denotes Reserved Bits |
