Note 1: Please refer to DMAC precautions.
Note 2: Set DMA inhibit before changing the DMA request cause. Set DRQ to "1"
Note 3: DMA0-INT0, DMA1-INT1, DMA2-INT2, and DMA3-INT3 correspond to DMAi and
Note 4: UARTi reception and ACK switching are effected using the UARTi special mode
Note 5: When setting DSR to "1", set DRQ to "1" using OR instruction etc. simultaneously.
Note 6: Do not write "0" to this bit. There is no need to clear the DMA request bit.
Nothing is assigned.
When write, set "0". When read, its content is indeterminate.
