Because sector 1 and 2 are on the same flexNVM block, read data cannot be guaranteed from a Flash block that is being writen.
Thanks for respose,
Can you please explain in more details why read data is not garantee during writing to the same block? Is it just protection issue?
I found the explanation in the K60 manual:
Flash Reads and Ignored Writes
The FTFL module requires only the flash address to execute a flash memory read. MCU
read access is available to all flash blocks.
The MCU must not read from the flash memory while commands are running (as
evidenced by CCIF=0) on that block. Read data cannot be guaranteed from a flash block
while any command is processing within that block. The block arbitration logic detects
any simultaneous access and reports this as a read collision error (see the
