Reading flash in a DMA int. routine. - Steve Sabram - Aug 16 21:38:34 2008
I have a piece of code that is reading the ADC12 and writing it into
flash via a DMA on the F168. I have an interrupt generated (DACDMA)
after every page is written to check its values. The routine increments
the DMA0DA to a new flash page and then reenables the DMA. When I don't
read the flash memory contents, it goes along fine filling up the flash
from the ADC12, however, whenever I read the latest page of flash
memory, the DMA interrupt is no longer generated. I have done the usual
putting FWKEY into FCTL1 and FCTL3 to erase the memory but so far I
can't get any more interrupts generated. Any ideas?
