Hello @Skannan,
There is C40 flash controller.
Please refer to the RM for more information about it:
Chapter 20 Embedded Flash Memory (c40asf).
The RTD has low-level drivers (examples are labeled as Ip) and high-level MCAL drivers.
FEE and FLS drivers are the high-level MCAL drivers for flash/eeprom.
Whereas C40 is a low-level flash driver.
