AM335x PORz引脚能否作为CPU外部复位输入信号



我们设计中希望用 PORZ 引脚作为CPU的外部全局复位输入信号,通过板上的CPLD来对CPU复位,然后使用CPU输出的WARMRSTn信号来对板上其他外设进行复

位。但是我看芯片datasheet上有这样说明:

When power and cloWhen power and clocks to the chip are stable, PORz must be de-asserted.cks to the chip are stable, PORz must be de-asserted.

这对器件会哪些影响?会不会损坏器件?

谢谢!
