Recently my code size grew so big that I only have a couple of bytes remaining in flash.
Normally I would program the BLB0 and BLB1 as follows:
BLB0: LPM and SPM prohibited in Application Section
BLB1: LPM prohibited in boot section.
I have no boot loader code. But my code has always been so large that it flowed into the boot loader flash area.
Now that I have very little flash remaining, these settings fail. Why?
Without these settings, I guess the LPM and SPM instruction are now able to be executed...should I be concerned?
