7-5. Microprocessor Interface

The peripheral block diagram of the microprocessor shows in Fig. 7-5-1. All kinds of control such as signal SW, etc. are carried out by the I2C of microprocessor. The level control of RGB signal process IC (QB024: M52320SP) and the sync polarity information of the sync process IC (QB012: M52347FP) are carried out in QB025 (CXA1315M). Refer to table 7-5-1 for the logic about the polarity information of sync signal.

RGB/VIDEO SW, Audio mute/volume adjustment, etc. are controlled in QV045 (CXA1315M). Further, using camera or not, camera zoom and focus adjustment controls are carried out in QV057.
