9. DVD Part: Introduction of MTK1379 maintenance Under normal power supply conditions, the maintenance plan for MT1379 mono-chip is: first the reset circuit resets the MT1379, after the crystal oscillator circuit gave the clock signal to MT1379, MT1379 will start the initialization check for Flash、E PROM、SDRAM, after everything is checked to be normal, it will start initialization check for 7Audio DAC, MT1336 and motor Driver. -
