Internal Flash
64KB (8KBx8)
Supported Regions
0x0000_0000 - 0x0000_FFF7 (Program Flash)
0x0010_0004 - 0x0010_0007 (CR-Trimming Word)
CR Trimming Word
Pay special attention to the CR-Trimming Word!
Erasing the last 8KB Block also erases the CR-Trimming Word
If the last 8kB block is used or a CHIP-erase is executed, the CR-trimming should be read out beforehand and reprogrammed again later on
This process can be automated as follows:
JFlash.exe -openprjc:\temp\mb9t.jflash -readchip -delrange0x0,0xFFF7 -saveasC:\Temp\Trim.mot -openC:\temp\userData.mot -delrange0x100004,0x100008 -mergeC:\Temp\Trim.mot -auto -exit
Make sure that the paths and filenames are customized according to your needs
