SPI Control Register
Register Name:
Access Type:

•
100
SPIEN: SPI Enable
0 = No effect.
1 = Enables the SPI to transfer and receive data.
SPIDIS: SPI Disable
0 = No effect.
1 = Disables the SPI.
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.
SWRST: SPI Software reset
0 = No effect.
1 = Resets the SPI.
A software-triggered hardware reset of the SPI interface is performed.
