This is closely related to Flash block question on MK60FN1M0VLQ12?
I would like more clarification on this.
Specifically, If I run a block command in FTFE (eg. block erase check (FCCOB0:FCMD = 0x00), or block erase (FCCOB0:FCMD = 0x08)) does the command operate on 256K or the 512K "combined block"?
PEx tends to refer to the "combined blocks".
The datasheet still seems to use the word "block" for two different things.
