Module CRC32 value
Computed for module data
When the module first starts up or recognizes an initialization of the
processor, it will compare the values of the two CRC’s in the input and
output images. If either one of the CRCs do not match, the module will
be placed in Stop mode. If each set matches, the module will be
placed in Operate mode.
