SPI: reading MISO status

[Vala]

Hi,

What is the status of a MISO pin of an SPI instance after issuing NRF_GPIO->IN? Does it reflect the real state of the pin? If no, what fast options do I have to read the status of MISO pin of SPI?

Looking at the figure given in the specification here it clearly shows that they are routed through GPIO module. But it cannot be read as this is an output pin. You need to wire this in to another GPIO to read it using GPIO->IN

Thanks for your perfect answer. I like it when I am referred to the specification.
