SC_TXDMARST: Setting this bit resets the transmit DMA. The bit clears automatically.
SC_RXDMARST: Setting this bit resets the receive DMA. The bit clears automatically.
SC_TXLODB: Setting this bit loads DMA transmit buffer B addresses and allows the DMA
controller to start processing transmit buffer B. If both buffer A and B are loaded simultaneously,
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.
SC_TXLODA: 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,
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.
SC_RXLODB: Setting this bit loads DMA receive buffer B addresses and allows the DMA
controller to start processing receive buffer B. If both buffer A and B are loaded simultaneously,
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.
