Microprocessor

Figure 9-40 Micro processor

The HDR2K3 has two microprocessors. The microprocessor,
OTC, located on the SSB, 7001, is the main processor for the
set. When Power is applied to the set and the Mains switch is
turned "on", the processor monitors the Keyboard and IR
receiver located on the Sensor Board. This IC controls the
functions on the SSB, Video switching on the SSM, and the
PIP/DW panel. A ROM located inside the IC has the Startup
program. The main program to run the processors is located in
the Program Flash RAM, 7006. IC 7012 is used by the OTC for
temporary storage. IC 7007 is used to store data for Teletext.
There are three I2C busses, a fast bus, F, a slow bus, S, and a
TX bus to communicate with the microprocessor on the ACS
module. The NVM 7011 stores settings such as customer
preferences, OPT numbers, Tuner settings, and Error codes.
composite video is fed to pin 5 for decoding Teletext and
Closed Caption information. In the Standby mode, Power is not
applied to the processor on the ACS module.

The microprocessor, 7100, located on the ACS module,
controls the Convergence, Geometry, and CRT drive circuits.
Settings for Convergence, Geometry, and White drive are
stored in the NVM, 7000. This IC is 512K for the AP sets and
256K for the Korean version. When 7100 reads the size of
7000, it then determines which software to load. If it reads 512K
present, the AP software is loaded. If it reads 256K, NTSC only
software is loaded. Commands for the ACS processor are
produced by the OTC on the SSB and transmitted via the TXD
and RXD lines.

Front Control Panel

Figure 9-41 Front Control Panel

The Front Control panel has the Power LED, Keyboard, IR
Receiver, and Light Sensor. The Keyboard is a resistor ladder.
The voltage changes value depending on which selection is
made. The voltage on this line will be 3.3 volts if no buttons are
selected. The two-colour LED indicates the status of the set. In
the Standby mode, the ON_OFF_LED line is High and the +9-
volt source is turned "off". In this case, the RED LED is lit.
When the set is turned "on", the +9-volt source is switched "on",
turning the Green section of the LED "on". The LED then turns
Yellow. When the set is fully "on", the ON_OFF_LED line goes
Low, turning the Red LED "off". The indicator is now Green.
The IR Receiver, 6105, receives commands from the remote
control.
