buffer A will be used first. This bit is cleared when DMA completes. Writing a zero to this
bit has no effect.
Reading this bit returns DMA buffer status:
0: DMA processing is complete or idle.
1: DMA processing is active or pending.
Setting this bit loads DMA transmit buffer A addresses and allows the DMA controller to
start processing transmit buffer A. If both buffer A and B are loaded simultaneously,
