2.2.2 UOC-III (ULTIMATE-ONE-CHIP)
UOC3 is composed of microcontroller, video proccessor, sound proccessor and IF blocks. So, there
are digital and anolog parts in it named as Picasso and Cosmic respectively as shown below ;
UOC3 has standard and face down versions, pin squence differs between two version. After
