ZHCSA85F August 2012 – February 2019 DLPC410
The DLPC410 contains a watchdog timer that initiates a global DMD Mirror Clocking Pulse in the event that the DMD has not received any Mirror Clocking Pulse by the user within the last 10 seconds. This auto-generated Mirror Clocking Pulse function is to provide Mirror Clockling Pulses to the DMD mirrors to prevent long term landed mirrors in the event the input data and source control has been inadvertently disrupted. This capability can be user disabled by setting WDT_ENABLE to logic '1'. Note that the global DMD Mirror Clocking Pulse generated by the watch dog timer is asynchronous to any/all activity on the DMD input data bus - therefore there is no guarantee as to the validity of the data displayed on the DMD once this pulse occurs, at least until new data is subsequently loaded and displayed.
