TM External Pins
EachoftheTMs,irrespectiveofwhattype,hasoneTMinputpin,withthelabelTCKn.TheTM
inputpin,isessentiallyaclocksourcefortheTMandisselectedusingtheTnCK2~TnCK0bitsin
theTMnC0register.ThisexternalTMinputpinallowsanexternalclocksourcetodrivetheinternal
TM.ThisexternalTMinputpinissharedwithotherfunctionsbutwillbeconnectedtotheinternal
TMifselectedusingtheTnCK2~TnCK0bits.TheTMinputpincanbechosentohaveeithera
risingorfallingactiveedge.
TheTMseachhaveoneormoreoutputpinswiththelabelTPn.WhentheTMisintheCompare
MatchOutputMode,thesepinscanbecontrolledbytheTMtoswitchtoahighorlowlevelor
totogglewhenacomparematchsituationoccurs.TheexternalTPnoutputpinisalsothepin
wheretheTMgeneratesthePWMoutputwaveform.AstheTMoutputpinsarepin-sharedwith
otherfunction,theTMoutputfunctionmustrstbesetupusingregisters.Asinglebitinoneofthe
registersdeterminesifitsassociatedpinistobeusedasanexternalTMoutputpinorifitistohave
anotherfunction.ThenumberofoutputpinsforeachTMtypeanddeviceisdifferent,thedetailsare
providedintheaccompanyingtable.
AllTMoutputpinnameshavean"_n"sufx.Pinnamesthatincludea"_1"or"_2"sufxindicate
thattheyarefromaTMwithmultipleoutputpins.ThisallowstheTMtogenerateacomplimentary
outputpair,selectedusingtheI/Oregisterdatabits.
