    HS3 Vref

    @JColvin Thanks for the quick response! So it sounds like Vref has to be on all of the time and if it ever drops to 0V the JTAG buffers will turn off. Thanks, Brandon

    HS3 Vref

    EENew24 posted a question in Other

    Hello, I want to use the HS3 but we unfortunately dont bring out the VREF voltage to your programmer. How is VREF handled on the HS3 programmer? Is sampled on startup and latched into place? If we tied it to your SRST, which is pulled up to 3.3V, on our board would that work or if SRST is set low will that cause issues for VREF? Thanks, Brandon
