Increasing Flash Write Speed in MPC5674

Hi There,


I'm trying to look for some improvements to writing to internal flash on the MPC5674.  Currently to write large amounts of data we're having to suspend write operations, and resume regular program flow until we have enough time to continue writing to flash, and repeat this process.  This is due to the fact that writing can take up to 500us, according to the datasheet, which is too long to write large multi-KB data without pausing to process other events.


From my understanding it's not possible to write more than 128 (or 256) bits at once, so is there another way of increasing write speeds?
