Introduction In comparison to the older TVPO 2065 hardware, the port 3 of the TVPO 2066 consists of 6 x 12 V/2 mA open­ drain outputs instead of 5 V/25 mA open­drain outputs. "TVPO 2066" is the name of the unprogrammed hardware. The programmed versions will be called: ­ TVPO 2066­Axx ­ TVPO 2066­Dxx for analog TV­sets for digital TV­sets 2. The Functional Blocks of the TVPO 2066 The hardware components of the TVPO 2066 are: ­ 8048­core, fully compatible to 8048 instruction set ­ 10K ROM, 256 byte RAM ­ four 64 steps analog output to control vol., color etc. ­ single 4032 steps analog output for controlling of a VS­tuner ­ IR decoder for ITT­IR (remote control with IRT 1250/60) ­ mains flip­flop for standby mode ­ IM­bus interface for non­volatile memory and devices of DIGIT 2000 system for digital video­processing. ­ fast counter input (T1) for automatic search (for analog TV­sets) ­ 12 digital combined inputs/outputs (8 or 10 for DIL­ package) ­ 8 digital outputs ­ integrated 12­digit on­screen display 2.1. The 8049 Microcomputer For the description of the commands and characteristics of the 8049, please refer to the CCU 2030, CCU 2050, CCU 2070 data sheet. The 8049 provides separate address space for program, data, in/out, and external data. The ROM is organized in banks of 2 K Bytes. Bank 0 occupies the addresses 0 to 2047. The other banks (10, 11, 12, 13) share the addresses 2048 to 4095. The different banks are selected through the bank select register 15 as described for the CCU 2070 in the CCU 2030, 2050, 2
