Does setting down SPIS_CSN_PIN for one SPI instance affect the other?

[ndarkness]

Hello,

I have a brief question regarding to SPI, I have two instances of SPI, SPI0 and SPI1, I was wondering whether or not changing the value of SPIS_CSN_PIN to SPI0 would affect to SPI1 and viceversa. Could you enlighten me ?

Also related, if I my spi_write() method inclue the following loop, I make my function blocking right?

  while (!spi_xfer_done_SPI0) {
    __WFE();
  }

How can I make it not blocking?

Thanks again,

Which SDK version are you using? Are you using SPI slave or SPI master? If you have defined SPIS_CSN_PIN, and assigned this as the CSN pin for both interfaces, it will affect both SPI0 and SPI1. You should use different CSN pins for the two instances.
