Their single cycle instruction and 2-stage pipeline architecture make them suitable for high speed applications. As the devices include an VFD driver they are suitable for use in products which require a front panel for their operation such as DVDs, VCDs, Mini-ponent audio systems, cassette decks, tuners, CD players, other home appliances, etc. Rev. 1.00 April 20, 2006 HT49RV9/HT49CV9 Block Diagram In te rru p t C ir c u it P ro g ra m R O M P ro g ra m C o u n te r S ta c k IN T C T M R 0 C T M R 0 P F D 0 T M R 1 C T M R 1 P F D 1 M P r e s c a le r X P D 6 /T M R 0 P D 7 /T M R 1 U X f...
