Periodic Type TM Register Description
OveralloperationofthePeriodicTMiscontrolledusingaseriesofregisters.Areadonlyregister
pairexiststostoretheinternalcounter10-bitvalue,whiletworead/writeregisterpairsexisttostore
theinternal10-bitCCRAandCCRPvalue.Theremainingtworegistersarecontrolregisterswhich
setupthedifferentoperatingandcontrolmodes.
