PGA900: OTP Checksum and MCU_MON Register

Part Number: PGA900

Hi,


I`ve got two questions about thePGA900 and the similar products of the PGA900.

Does perform the PGA an internal OTP Checksum check? And what happens if it goes wrong?

Is there a description of the MCU_MON Register available?

  • Hello Mario,

    There is no integrated OTP checksum function in the PGA900 or PGA902. A checksum feature will have to be implemented in the user's firmware if it is desired.

    The MCU_MON register in the PGA902 will read out the current program address. This can be used for debugging if the processor hangs on a particular command. The micro must be in reset to read this register through the digital interfaces, though.

    Regards,

  • Hello Scott,

    thanks for your fast response.


    I´ve got two additional questions...


    Is there any additional register which shows the state of the MCU e.g. internal exception, internal error, Interrupt?


    How can compare the program address of the MCU_MON Register, with my code?

  • Hello Mario,

    There are no additional status registers pertaining to the microcontroller unfortunately. The MCU_MON register contains the instruction fetch address. This should match the addresses that are in the assembly code.
