Bits [12:0] SC_RXCNTB: The offset from the start of DMA receive buffer B at which the next byte will be
Bits [12:0] SC_RXCNTSAVED: Receive DMA count saved in SPI slave mode when nSSEL deasserts.
Bits [12:0] SC_RXERRA: The offset from the start of DMA receive buffer A of the first byte received with a
Saved receive DMA count register (SCx_RXCNTSAVED)

register is written when the buffer is not loaded, the buffer is loaded.
The count is only saved the first time nSSEL deasserts.
parity, frame, or overflow error. Note that an overflow error occurs at the input to the receive
FIFO, so this offset is 4 bytes before the overflow position. If there is no error, it reads zero. This
register will not be updated by subsequent errors until the buffer unloads and is reloaded, or the
receive DMA is reset.
