    [Quark D1000/D2000] SPI Master - Slave Select Operation?




      From D1000/D2000 datasheets it can be seen that there are 4 SS (Slave Select) pins that can be controlled by the SPI master peripheral itself.


      D1000 pin names MST_M2SS[3:0]

      D2000 pin names SPI_M_SS[3:0]


      Question 1.

      Are these 4 pins mutually exclusive with lets say 1 being used as a Slave Select and the other 3 as GPIO ?

      Question 2.

      Is the D1000 operation the same as the D2000 operation in this case ?

      many thanks,
