    Resolved
    The G2221 has only one calibrated frequency (1MHZ), and it's at 0x10FE-FF. Did you look that far? I wonder if maybe Elprotronic is checking for the 4x that some other G2 devices have. There is a download option to erase "protected information memory…

    Sorry for being vague. The issue is that Code Composer Studio wont detect the MSP430g2221 for programming.

  • RE: Looking for PMIC

    Hi Chao, I don't think we have any PMICs that would support that behavior by default, however it might not be too difficult to implement a circuit to handle it. I think some combination of an NE555, a NAND gate, and a latch maybe could control an enable…
