MSP430F6775: Can I use the IAR Embedded Workbench IDE to get the value of the register

Hi

I would like to read the value of the registers in the SLAA577G - MSP430F677x(a) based MCU using JTAG.

 

I think I need to use the Isolation Plugin Board, but how do I connect?

 

  1. Connect the J101 pin of the Isolation Plugin Board to the MSP-FET.
  2. Isolation Plugin Board J2 odd pin on SLAA577G - MSP430F677x(a) Connect to the JTAG port.

 

If I did 1. 2 above, can I use the IAR Embedded Workbench IDE to get the value of the register?

    Hello Tsurumoto,

    If this is a new design, I would recommend that the customer use the Energy Measurement Design Center (EMDC) and related software library. The code related to SLAA577 should be used as a reference for existing designs.

    That is possible.

    Are you referring to the MSP-ISO board? If so, that may be possible if you use 2-wire SBW. Isolation is typically required when debugging the MSP430 while high voltage is connected to the board. However, if you are certain that Neutral is connected to the board ground instead of Line, isolation may not be required for debugging. Caution must be exercised though.

    Yes. Consider using CCS since EMDC does support both CCS and IAR.
