On the datasheet of 21469 processor, I see that the DPI pins can be in the three-state condition (page 14). But the DPI pins have a default routing configuration after the processor is reset.
Now, DPI pins 1-4 are by default routed to SPI peripheral. So I see that if the processor is configured to boot in SPI Master mode, these pins would not be in three-state after reset.
I would like to know if it is possible to bring these pins (DPI pins 1-4) to three-state condition and if yes how it can be acheived.
