TMS570LS3137: Why does the Het2ParityCheck read from ESM group1 channel 34 (reserved in TRM)?

Part Number: TMS570LS3137


I am using this code in a DO178C (FAA) compliant program, so ALL code must originate from SW requirements and have technical documentation. 

In the Het2ParityCheck sample code, post-test, the code checks for ESM group1 channel 7 (which is documented) AND ESM group1 channel 34 (which is marked as reserved in the current datasheet). Can you tell me why channel 34 is checked?

Thanks,

Jim
