TMS570LS1114: Parity check address order of TMS570LS1114

Part Number: TMS570LS1114

hi,when i called SL_SelfTest_VIM(), type  is VIM_SRAM_PARITY_TEST,

When I test the interrupt vector table 0xFFF82000, the corresponding parity check bit (address 0xFFF82403), read the value of address 0xFFF82000, the self-check failed, and also entered the interrupt of abnormal data, resulting in 2 bit Flash ECC failure, may I ask what is the reason?

The previously recovered TMS570 is the large endian sequence,

data                 parity

0xFFF82000 0xFFF82403

0xFFF82004 0xFFF82407

0xFFF82008 0xFFF8240B

0xFFF8200C 0xFFF8240F

Interrupt vector table address 0xFFF82008, corresponding parity 0xFFF8240B, this group of tests can pass, I am wondering, why 0xFFF82403 corresponding to 0xFFF820080 is not correct, but 0xFFF82400, can pass the test
