ZHCSA85F August 2012 – February 2019 DLPC410
The INIT_ACTIVE signal indicates that the DMD, Digital Micromirror Driver, and the Digital Controller are in an initialization state after power is applied. During this initialization period, the DLPC410 is calibrating the data interface, initializing the DMD, and DLPA200(s). When this signal goes low, the system has completed initialization. System initialization takes approximately 220 ms to complete. Data and command row cycles must not be presented to the DLPC410 during the initialization. INIT_ACTIVE should be considered an asynchronous feedback signal to the user. Standard synchronization techniques should be applied. After initialization is complete, a delay of at least 64 DCLKIN clocks (on all input data buses being used) should be observed before the first DVALID is asserted on those data buses to ensure a clean start up process.
Note: NS_FLIP, COMP_DATA, and RST2BLK signals should be kept low ('0') during initialization to ensure proper system setup.
