Circuits to interpret pin inputs
In examples, an apparatus comprises a pin, an input buffer coupled to the pin at an output of the input buffer, a voltage divider circuit coupled to the input buffer at an input of the input buffer, a first current mirror coupled to the input buffer, and a second current mirror coupled to the input buffer. The apparatus also comprises a first output buffer coupled between the input buffer and the first current mirror, and a second output buffer coupled between the input buffer and the second current mirror.
