0: No effect.
1: The current NPCS will be deasserted after the character written in TD has been transferred. When CSAAT is set, 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: No effect.
1: 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
0: No effect.
1: Disables the SPI.
As soon as SPIDIS is set, SPI finishes its tranfer.
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 control register is written, the SPI is disabled.
0: No effect.
1: Enables the SPI to transfer and receive data.
