Use this option to specify individual bits to test when comparing values. Testing is performed as follows:

• a binary zero in the filter indicates that the bit is not tested

• a binary one indicates that the corresponding bit of the transfer is compared with the corresponding bit of the Data value.

When you select the option, RealView Debugger inserts $MASK$=0xFFFFFFFF in the textbox. Enter the value that you want to compare against, and edit the mask to the required value.
