DMA Receive Transaction Count
When using DMA to receive SPI data without transmitting data, this register can be used in
conjunction with the control bit SPI0_CTL.RXTCNTEN to set number of transactions to
perform. Without this, the SPI interface will only initiate a transaction when it receives a
request from the DMA system, resulting in a lower achievable data rate.
