Part Number: TMS570LS3137 Hi, I am trying to perform HET1 RAM Parity test, below is the steps i am executing: 1. Write known value to 0xFF460000 HET RAM address say (0xFFFFFFFF) 2. Disable HET1 RAM parity. 3. Toggle bit Zero of data at HET RAM address 0xFF460000. 4. Enable HET1 RAM parity. 5. Read data from 0xFF460000 HET1 RAM address but when when i write 0xFFFFFFFF to HET RAM address 0xFF460000, i could see 0x03FFFFFF in the memory browser. some how i could get any details in TRM why first 6 bits are not able to write? Can you please help me in understanding this issue? Thanks, Kalyan
