0842.N0.139.pptxHello,
Please answer following question.
Q1:
I want to know the behavior of TPS65381 with following operation.
1) Set DIAG_EXIT=0 and DIAG_EXIT_MASK=1 in DIAGNOSTIC state.
2) Set DIAG_EXIT_MASK=0
3) Dose TPS65381 go to SAFE state or stay DIAGNOSTIC state?
Q2:
I tried to test above operation using TPS65381EVM but I could not set DIAG_EXIT=0 in DIAGNOSTIC state. ( I cricked DIAG_EXIT field but it returned to checked as below.)
Please advise why I could not set DIAG_EXIT=0.
Cleared ERR_FAIL and WD_FAIL flags are set after set DIAG_EXIT=0 (SPI_WRITE 0x49 ; 0x16).
Please advise why these flags are set.
Best Regards.
