    • A memory unit includes a memory organized into protected and non-protected areas. A controller manages access to the memory so that the protected area can be written to through a JTAG or CPU interface. Once written to, the protected area is only accessible to particular logic and cannot be over-written until the entire memory is erased. The controller is configured to allow a BCV to be stored in the memory through either the JTAG or CPU interface. The controller is also configured to allow writing to the protected area and boot configuration vector in memory before CPU boot-up by using a JTAG clock signal provided through an external pin when a system clock signal is not available. A reset circuit generates one or more initialization signals using either the BCV from memory or another BCV provided on external BCV pins, depending upon whether another external BCV pin is asserted.
    • 存储器单元包括组织成受保护区域和非保护区域的存储器。 控制器管理对存储器的访问,以便可以通过JTAG或CPU接口写保护区。 一旦写入,保护区只能访问特定的逻辑,并且不能被覆盖,直到整个内存被擦除。 控制器配置为允许通过JTAG或CPU接口将BCV存储在存储器中。 控制器还配置为在系统时钟信号不可用时,通过使用通过外部引脚提供的JTAG时钟信号,在CPU启动之前,将写入保护区域并启动存储器中的配置向量。 复位电路使用来自存储器的BCV或外部BCV引脚上提供的另一个BCV产生一个或多个初始化信号,这取决于是否断言另一个外部BCV引脚。
