Kinetis KX0 - get program flash sector size

Hello,

I would like to know hot to get information about program flash sector size from the uC?

Is it true that bits 8:7 of the SIM_SDID register reflects the sector size?

Thanks for the answer and bets regards.

To the best of my knowledge, you can't get sector size directly. But any Kinetis family member working on frequency 120/150MHz uses phrase (64 bits) programming - sector size is 4KB. Kinetis devices running on 100MHz or less uses longword (32 bits) programming - sector size is 2KB. So the max. frequency of operations gives indirect information about sector size.
