Hi,

no, MPC5643L does not have data flash. If you need to write data to flash in run time, you can use small blocks in low address space (the number of program/erase cycles for blocks in low address space is higher than for block in mid or high address space). You can use either standard software driver to write the flash:

or Emulated EEPROM driver:

Can I use both the drivers in the same application? but for different purpose ( one for code flash other for data) Just curious if there is going to be a mismatch in register configuration
