20 represents a bit connected to a particular pin, or "ball" on Ball Grid Array
30 also "GPIO Expander" chips that connect using the I2C or SPI serial buses.
38     value might be driven, supporting "wire-OR" and similar schemes for the
42     of pins configured as "output", which is very useful in such "wire-OR"
50   - Usually a GPIO will be configurable as either input or output, as needed
73 GPIO may be inverted before is reaches its destination, or a device could decide
76 being either active-high ("1" means "active", the default) or active-low ("0"
83 level is actually driven), or "open source" (where only the high signal level is
85 used for TTL. A pullup or pulldown resistor causes the high or low signal level.
86 This is sometimes called a "wire-AND"; or more practically, from the negative
87 logic (low=true) perspective this is a "wire-OR".
95 that can be used as either an input or an output:
101  the pullup (or some other device) controls the signal.
