1: The current NPCS will be deasserted after the character written in TD has been transferred. When CSRn.CSAAT is one, this
allows to close the communication with the current serial peripheral by raising the corresponding NPCS line as soon as TD
transfer has completed.
0: Writing a zero to this bit has no effect.
1: If The FIFO Mode is enabled (MR.FIFOEN written to one) and if an overrun error has been detected, this command allows to
empty the FIFO.
0: Writing a zero to this bit has no effect.
1: Writing a one to this bit will reset the SPI. A software-triggered hardware reset of the SPI interface is performed. The SPI is in
slave mode after software reset. Peripheral DMA Controller channels are not affected by software reset.
0: Writing a zero to this bit has no effect.
1: Writing a one to this bit will disable the SPI. As soon as SPIDIS is written to one, the SPI finishes its transfer, all pins are set
in input mode and no data is received or transmitted. If a transfer is in progress, the transfer is finished before the SPI is
disabled. If both SPIEN and SPIDIS are equal to one when the CR register is written, the SPI is disabled.
0: Writing a zero to this bit has no effect.
1: Writing a one to this bit will enable the SPI to transfer and receive data.
0: Writing a zero to this bit has no effect.
