Occasional ContributorHPS SPI MISO pin
I have a question about HPS SPI pin, MISO. It's HPS dedicated pin once configured.
Was it able to MUX it with a HPS GPIO pin internally? Which means either one of them can go to HPS SPI controller...

Regular ContributorHi,
I did not get the device that you are using, which device are you referring to? Cyclone V SoC, Arria 10 SoC etc.

Does the SPI controller support 3-wire SPI?

Any updates? Thanks.

Hi,
There are two MISO signal pins available for the SPI masters and SPI slaves. Theses pins are routed and available to the HPS I/O, yes it can go to the SPI controller.
I recommend that you read our Arria 10 SoC HPS TRM SPI Controller section [page 3925], for more detailed information on the usage and interfaces of the SPI controller:
