Microprocessor
Figure 43
The HDR2002 has two microprocessors. The Microprocessor, 7001, on the SSB monitors the
Keyboard and the Remote sensor during standby. This IC controls the Tuner, Video switching on the
SSB, generates the consumer OSD.
Pin 5 of 7001 monitors the Keyboard for a voltage change to generate a command. The Front Detect
line on Pin 6 monitors the AV inputs on the Side Jack panel. If a problem develops, the Front Detect
will go Low, preventing 7001 from receiving any commands. The Power Fail input on Pin 79 goes
High if the set looses power while the set is On. Composite Video is fed to Pin 31 for Closed Caption
decoding. Horizontal and Vertical sync on Pins 53 and 55 synchronize the OSD and Closed Captions
display signals, which are output on Pins 46, 47, and 48. Fast Blanking for the OSD is output on Pin
52.
There are three I2C busses on 7001. The Bus on Pins 78, 80, and 97 communicates with the Memory
IC 7012. This IC stores Customer setup information, Option codes, and Error codes. I2C busses, S
and F communicate with the Tuner on the PIP panel, and the ICs on the SSB. The S bus also controls
the Tuner on the SSM and the Audio and Video switching on the SSM. Data lines on Pins 16 and 17
communicate with the Microprocessor on the ACS module.
