3.1.29.2 Write Parameters

Table 3-23 describes the command parameters.

Table 3-23 Write Parameters

Parameter Bytes	Description
Byte 1	Batch file number

This command executes a batch file stored in the flash of the display module. Any system write command that can be sent by itself can be grouped together with other system commands or command parameters into a flash batch file, with the exception of all read commands.

The flash batch file numbers specified in this byte are enumerated values (such as 0,1,2,3). Flash batch file 0 is a special auto-initialization batch file that runs automatically by the DLPC34xx software immediately after system initialization is complete. The flash batch file 0 is typically not called using the Write Execute Batch File command (although the system allows it). This special flash batch file specifies the source to be used (such as splash screen or data port) once the system initializes.

Embedding flash batch file calls within a flash batch file is not allowed (for example, calling another batch file from within a batch file is not allowed). To execute two batch files back to back, use back to back execute batch file commands.

The system allows adding an execution delay between commands within a flash batch file, which is done using the Write Flash Batch File Delay command.

The order of command execution for commands within a flash batch file is the same as if the commands are received over the I²C port.
