Using SPI1 in the MK20DX256VLH7

I'm trying to use the second SPI module in the MK20DX256VLH7 (as a slave), but I don't see SPI1_SCK listed anywhere in the pinout table. What pin should the SPI1 clock be connected to?


Also, SPI1_PCSx isn't listed in the "Technical Data" document K20P64M72SF1 Rev 3, 11/2012 table on page 62.  The "Reference Manual" document K20P64M72SF1RM, Rev. 1.1, Dec 2012 table on page 207 does list SPI1_PCS1 (on pin 1, alternate 2).  But it doesn't list SPI1_PCS0, which I think is the only PCS that can be used as input for a slave; see Table 10-28 on page 217.


Does anyone know how to use SPI1 in this chip, particularly as a slave?  Thanks.
