When the factory burns G48, it needs to write a ID number in each flash of MCU, ID can be incremented. What kind of recorder can be used to achieve it? How do you realize it? Thank you
Hi Gary Guo,
On the MCU is available Program Once Field. It is a part of Flash IFR which can beused to store non-volatile data.The global memory from 0x0_4000 is accessible when we set NVMRES bit(MMCCTL1=0x01;) at PPAGE 0x01 and memory window 0x8000~0xBFFF.
See Table 24-5. Program IFR Fields in the reference manual. Programming the own serial number is possible into Program Once Field - 64Bat global address 0x0_40C0 – 0x0_40FF.
