Bits [0] SC_UARTFRAC: The fractional part of the baud rate period (F) in the equation:
DMA channel registers
Serial DMA control register (SCx_DMACTRL)
Address offset: 0xC830 (SC1_DMACTRL) and 0xC030 (SC2_DMACTRL)
Reset value:
Bit 5 SC_TXDMARST: Setting this bit resets the transmit DMA. The bit clears automatically.
Bit 4 SC_RXDMARST: Setting this bit resets the receive DMA. The bit clears automatically.
Bit 3 SC_TXLODB: Setting this bit loads DMA transmit buffer B addresses and allows the DMA
Bit 2 SC_TXLODA: Setting this bit loads DMA transmit buffer A 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.
