如何获取一个5606的串号或者CPUID,我已经读取配PVR和PIR,这个两个寄存器的值没有变化,看起来所有的单片机都是一样的。还有其他的编号可供读取用于设备记录吗?

Hi

I do not think it has dedicated register which can represent Unique Identifier to show the core,sub-family inf. But the DSC has JTAG ID,
and read SIM_MSH_ID/ SIM_LSH_ID, which are unique for each sub-family. For example, the MC56F8367 has a data for SIM_MSH_ID/ SIM_LSH_ID registers, but the MC56F8355 has another data for SIM_MSH_ID/ SIM_LSH_ID registers.

 


Have a great day,
Jennie Zhang
