PRODUCTION DATA
The reset active signal RST_ACTIVE goes high for approximately 4 µs, indicating a MCP operation is in progress. During this time, no additional MCPs will be accepted by the DLPC910 until RST_ACTIVE returns low. RST_ACTIVE does not return to low unless continuous no-op or data loading row cycles are issued.
RST_ACTIVE is asserted to indicate that the operation is in progress. Each RST_ACTIVE pulse applies to one or more MCPs depending on the reset block operation chosen from Table 7-12. RST_ACTIVE is synchronized to an internal version of DDC_DCLK. As such, circuits in the application FPGA should consider this signal asynchronous and use standard synchronization techniques to assure reliable registering of this signal.
