Standard TM Operation
ThesizeofStandardTMis16-bitwideanditscoreisa16-bitcount-upcounterwhichisdrivenby
auserselectableinternalorexternalclocksource.Therearealsotwointernalcomparatorswiththe
names,ComparatorAandComparatorP.Thesecomparatorswillcomparethevalueinthecounter
withCCRPandCCRAregisters.TheCCRPcomparatoris8-bitwidewhosevalueiscomparedthe
withhighesteightbitsinthecounterwhiletheCCRAisthesixteenbitsandthereforecomparesall
counterbits.
Theonlywayofchangingthevalueofthe16-bitcounterusingtheapplicationprogram,isto
clearthecounterbychangingtheTnONbitfromlowtohigh.Thecounterwillalsobecleared
automaticallybyacounteroveroworacomparematchwithoneofitsassociatedcomparators.
Whentheseconditionsoccur,aTMinterruptsignalwillalsousuallybegenerated.TheStandard
TypeTMcanoperateinanumberofdifferentoperationalmodes,canbedrivenbydifferentclock
sourcesincludinganinputpinandcanalsocontrolanoutputpin.Alloperatingsetupconditionsare
selectedusingrelevantinternalregisters.
