External SPI Chip select

Hi All,

 

             I am using K60N5112 on my custom board  with MQX3.8. I need to know more information on the SPI chip select (CS)

 

1) On my custom board I am using SPI1 with the following chips selects

SPI1_PCS1 (PTB9)

SPI1_PCS0 (PTB10)

External_CS_1 (PTB7)

External_CS_2 (PTB8)

SPI1_SCK (PTB11)

SPI1_SOUT (PTB16)

SPI1_SIN (PTB17)

 

 

Is it possible to use external chip selects with MQX3.8 and K60N512 ?

 

2) How do we select which ship select we want to use (suppose we first want to send data on device 1 using SPI1_PCS0 and then send data on device 2 using SPI1_PCS1) ?

 

Thanks,

Mohsin
