SCB in slave SPI mode - MISO tri state
Page 94 of the TRM (section15.2.2 and figure 15-1 specifically) shows that the SCB MISO line is tri-stated when the SCB is not selected by the SPI master. This is excellent news for me, but I don't see anywhere in that section where it is explicitly stated that the SCB tri-states the MISO line when the SCB is not selected.
Has anyone used the SCB where tri-stating the MISO line was a requirement in the design? I see a reference to SID172 and Thso in the AC characteristics but no timing diagram to give me the warm fuzzy feeling that these AC characteristics refer to what I think they refer to (how long it takes the SPI slave peripheral to tri-state MISO when the device is no longer selected).
