In security checks, we may involve detecting the following fault items,
When using MPQ7928, I did not find any register information related to these fault items in the manual. I would like to inquire which of these faults are supported by MPQ7928 to determine by reading register flag bits, or the corresponding register bit position information, such as:
1. ANALOG_SUILT_INDELF_TEST-ERR//Does it support obtaining the detection of this item through registers
2. OTP_CRC-ERR//Does it support obtaining the detection of this item through registers
3.REGISTER_CRC_ERR
4.REGISTER_WRITE_CHECK_ERR // 3 ， Are the errors related to register operations in the two designs judged through IIC returning read/write failures, etc.? Is it because the data in the register cannot be read normally in this situation, so it cannot be reflected on the register bit
5. VCC_UVLO_SRR//The UVLO fault item is mentioned in the introduction, but the corresponding read register cannot be found in the register manual. Can the status information still be obtained by reading the register in the undervoltage lock state? For example, when the power supply voltage (input voltage) of 7928 is particularly low, the chip will definitely not run and cannot read normally.
6. VNet PROCECTION-ERR//No relevant registers for device protection state detection were found. Can the device enter the protection state and read the registers normally to obtain its status.
7. REFERENCE_VOLTAGE-MON-ERR//Does it support detecting whether the fault of this item is triggered through register reading
The above are some questions raised during the development of some fault items. When searching the manual, I couldn’t find the corresponding information for these faults
Can you help me answer questions, thank you!
