E3930 Fast SPI interface for different slaves

Huuuyen — Wed, 23 Sep 2020 09:22:00 GMT

Hi!

We are working with E3930 microproccesor. We have the following doubt:
This processor has the Fast SPI interface specific for connecting two SPI Flash memories and a TPM device.
In our design we have only one flash memory connected to Chip Select 2 (BIOS), and TPM connected to Chip Select 0. Our doubt is if we can connect to Chip Select 1 a SPI device that is not a flash memory. Can we connect any other generic SPI device connected to this Fast-SPI interface?

Best Regards.
