Pin-remapping Functions
Theexibilityofthemicrocontrollerrangeisgreatlyenhancedbytheuseofpinsthathavemore
thanonefunction.Limitednumbersofpinscanforceseriousdesignconstraintsondesignersbut
bysupplyingpinswithmulti-functions,manyofthesedifficultiescanbeovercome.Thewayin
whichthepinfunctionofeachpinisselectedisdifferentforeachfunctionandapriorityorderis
establishedwheremorethanonepinfunctionisselectedsimultaneously.Additionallytherearea
seriesofPRM0,PRM1andPRM2registerstoestablishcertainpinfunctions.
Pin-remapping Registers
Thelimitednumberofsuppliedpinsinapackagecanimposerestrictionsontheamountoffunctions
acertaindevicecancontain.Howeverbyallowingthesamepinstoshareseveraldifferentfunctions
andprovidingameansoffunctionselection,awiderangeofdifferentfunctionscanbeincorporated
intoevenrelativelysmallpackagesizes.SomedevicesincludePRM0,PRM1orPRM2registers
whichcanselectthefunctionsofcertainpins.
