CR Trimming Word

Pay special attention to the CR-Trimming Word!
Erasing the last 8KB Block also erases the CR-Trimming Word!
Erasing the CR-Trimming Word only, also erases last 8KB Block!

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
