 Data registers must exceed starting registers. This is in the memory map
page that you printed.
 You must assign the PTQ module to a block of processor memory that is not
being used by any other device.
 You can use this simple formula to find a block of memory to use: If the
module consumes 224 words of status data on input, and we know that it can
take up to 768 words of I/O data, the total requirement is 992 words. The
module will take a maximum of this %IW value. For convenience, round the
number up to 1000 as the amount of memory to assign. A value of 5000 for
%MW and %IW is a safe starting point.
 It is not possible to determine if the memory values are correct before
building the project. If the build throws an error about memory addresses, go
back to ProSoft Configuration Builder and change the input and output
properties for the module, then re-import the memory map and try again.
To view memory usage in the processor
1 Start Unity Pro.
2 In the Project Browser, expand the Configuration tree, and then double-click
the L OCAL B US object.
3 In the L OCAL B US window, double-click the processor. This action opens a
tabbed window with information about the processor.
4 Click the C ONFIGURATION tab. This tab describes the processor's memory
configuration.
