I am confused in documentation.
1) In TWR-K60512 users manual there are SPI1 on B7 - B11 tower pins
B7 - SPI1_CLK usage PTE2
B8 - SPI1_CS1
B9 - SPI1_CS0 usage PTE4
B10 - SPI1_MOSI usage PTE1
B11 - SPI1_MISO usage PTE3
2) In K60 reference manual chapter 10.3.1 there is signal multiplexing and pin assignment
There are SPI signals described as SPI1_SIN, SPI1_SCK, SPI1_SOUT.
Why the different labeling of signals in documents for one device?
The last curious thing is that I found that the my software using SPI1 sends data on the B11 which is PTE3 - MISO or SIN!!!
