ZHCSE90D September 2015 – September 2020 DLPC910
The DLPC910 contains a watchdog timer that initiates a global DMD MCP in the event that any DMD reset block has not received a MCP within 10 seconds. This auto-MCP function can be disabled by asserting WDT_ENBLZ high. Disabling the watchdog is not recommended unless the user ensures that a MCP to the entire DMD occurs within 10 seconds. During the time when the DLPC910 is in idle mode or is not operating, it is recommended to exercise the DMD mirrors by continuously loading alternating all-on/all-off patterns.
