TMS320C6713B: 复位和时钟时序关系

Part Number: TMS320C6713B

您好!有以下几个关于TMS320C6713使用的问题需要请教下:
1)该芯片上电后,reset脚直接为高(没有复位过程)且同时外部有时钟输入,是否PC指针会运行内部RAM空间的代码?
2)在上述情况下,RAM中的代码是随机代码吗?
3)实际使用中,是否需要确保在reset为低时给时钟,待时钟稳定后再释放reset?

  • 1. 这个不确定,因为没有RESET信号,芯片就没有工作起来。

    2. RAM中是随机数值。

    3. RESET信号要在时钟和电源都稳定输出后再释放。这个在数据手册上有说明。

    As a best practice, reset should be held low during power−up. Prior to deasserting RESET (low−to−high transition), the core and I/O voltages should be at their proper operating conditions and CLKIN should also be running at the correct frequency.
