39     other value (notably, "open drain" signaling).
80 Open Drain and Open Source
82 Sometimes shared signals need to use "open drain" (where only the low signal
83 level is actually driven), or "open source" (where only the high signal level is
84 driven) signaling. That term applies to CMOS transistors; "open collector" is
89 One common example of an open drain signal is a shared active-low IRQ line.
90 Also, bidirectional data bus signals sometimes use open drain signals.
92 Some GPIO controllers directly support open drain and open source outputs; many
93 don't. When you need open drain signaling but your hardware doesn't directly
103 The same logic can be applied to emulate open source signaling, by driving the
104 high signal and configuring the GPIO as input for low. This open drain/open
