POWER ON RESET TIMING
In most case, the power of 90E36 and MCU are both derived from
220V power lines. To make sure 90E36 is reset and can work properly,
MCU must force 90E36 into idle mode firstly and then into normal mode.
In this operation, RESET is held to high in idle mode and de-asserted by
delay T1 after idle-normal transition. Refer to Figure-25.
