56 phrase "pin configuration node".
58 The pin configuration nodes act as a container for an arbitrary number of
60 pin, a group, or a list of pins or groups. This configuration can include the
61 mux function to select on those pin(s)/group(s), and various pin configuration
62 parameters, such as pull-up, drive strength, etc.
65 PIN CONFIGURATION NODES:
71 other words, a subnode that lists a mux function but no pin configuration
72 parameters implies no information about any pin configuration parameters.
73 Similarly, a pin subnode that describes a pullup parameter implies no
