C6414上电复位问题



使用的是C6414t-1G的芯片,供电芯片为TPS70345,3.3V,1.2V,复位信号和手动复位信号均由TPS70345产生,现在的问题是上电复位大部分时候不行,需要手动复位后才能正常工作。请问是什么原因呢?

  • 复位信号和手动复位信号在时序上有什么不同么?

    数据手册上要求"In addition, for proper device initialization, device reset (RESET) must be held active (low) during device power ramp and should not be released until the PLL becomes stable.",这点是否做到了?
