3.1. Input capabilities
There•are•2•active•high•inputs•(INPUT1•and•INPUT2).•This•GPIO•Type•1•input••provides•a•fixed•input•
detection•threshold•with•fixed•pull•down•resistance.
The•primary•function•of•the•inputs•is•to•provide•a•wake•on•ignition•feature•as•a•digital•input.•The•‘Wake•
Up’•functionality•is•software•configurable.
A•secondary•function•is•to•interface•with•switch•sensors•in•an•application.
The•following•table•provides•specifications•for•the•inputs:
