I'm reading a dsp manual and for many of the pins it says things like
"When the DSP is the bus master, ~BCLK is the inverse of BCLK signal. Otherwise, the signal is tri-stated."
What does it mean by "the signal is tri-stated"? Does it mean that its Hi-Z? It becomes a 3 state pin that is controllable or what?
Thanks, Jon
Yes, High Z
The term '3-state' is in fact a registered trademark of National Semiconductor. Hi-Z is the generic term for 'tri-stated' as Lax has pointed out.
From your brief description, the pin is always an output, and is driven while the device is bus master, otherwise Hi-Z. The only control over it would probably be the mode of operation as stated.

yep! Hi-z = Tri-stated
