3.25.1 Read

This command reads the Type of the Generic Command List given a Type Index. Generic Command List Type is used to group Generic Command Lists based on functionality. For example, all Command Lists that are related to flipping images may have the type as ‘Flip’. The Piccolo Software uses Command Lists of type ‘Internal’ to execute the System BIST (refer to Piccolo software for the Piccolo Software Programmer's Guide for the DLPC120 ASIC (DLPU061)) for more details on System BIST.
