15.1 Overview

TheMYXPM6021provides16GPIOpinsunderthecontroloftheSoC.ThemajorityoftheseGPIOpinshaveadefault

congurationasCMOSinputswithweak(50KOhm)pulldownsenabled.TheGPIObufferssupportoperationasopen-

drainorpushpulloutputs.Theyaresplitinto2groups,eachwithadifferentxedsupply:

• GPIO0P0–GPIO0P7supportalevelof1.8V

• GPIO1P0–GPIO1P7support3.3V

FollowingarethesupportedfeaturefromthedigitalGPIOIP:

• CMOSorOpenDrainoutputandinputconguration

• 2k-ohmor50k-ohmpull-uporpull-downresistance

• ReadbackofoutputPADvalues

• OutputLevelselectbyregister

• Digitalglitchlterof62μs

• Digitallter(de-bouncer,typically32ms)withprogrammablebypass

• Interruptandinterruptmaskfunctionality.

• Polarityselection(defaultactivehigh)

• Analog/DigitalInput

• Alternateinput/outputfunctionality.
