Arithmetic and Logic Unit – ALU
Thearithmetic-logicunitorALUisacriticalareaofthemicrocontrollerthatcarriesoutarithmetic
andlogicoperationsoftheinstructionset.Connectedtothemainmicrocontrollerdatabus,theALU
receivesrelatedinstructioncodesandperformstherequiredarithmeticorlogicaloperationsafter
whichtheresultwillbeplacedinthespeciedregister.AstheseALUcalculationoroperationsmay
resultincarry,borroworotherstatuschanges,thestatusregisterwillbecorrespondinglyupdatedto

Flash Program Memory
TheProgramMemoryisthelocationwheretheusercodeorprogramisstored.Forthisdevicethe
ProgramMemoryisFlashtype,whichmeansitcanbeprogrammedandre-programmedalarge
numberoftimes,allowingtheusertheconvenienceofcodemodificationonthesamedevice.
Byusingtheappropriateprogrammingtools,thisFlashdeviceoffersuserstheflexibilityto
convenientlydebuganddeveloptheirapplicationswhilealsoofferingameansofeldprogramming
andupdating.

TheProgramMemoryhasacapacityof4K×16bits.TheProgramMemoryisaddressedbythe
ProgramCounterandalsocontainsdata,tableinformationandinterruptentries.Tabledata,which
canbesetupinanylocationwithintheProgramMemory,isaddressedbyaseparatetablepointer
