2.3.10 Batch File Commands

During power-up and initialization or during normal operation, the DLPC900 can be commanded to execute a batch file containing a set of commands. The set of commands are created and saved in a text file.

If the batch file is added to the firmware it then becomes an additional part of the firmware and is uploaded into the flash memory. A batch file stored in the firmware that is specified to be the default batch file is executed by the DLPC900 during the power-up sequence.
