https://sourceforge.net/p/drake-devkit/feature-requests/3/Recent changes to 3: Add direct flash memory access opcode(s).enThu, 13 Oct 2005 17:04:09 -0000https://sourceforge.net/p/drake-devkit/feature-requests/3/<div class="markdown_content"><p>Similar to the internal EEPROM opcodes, we will need <br /> ways to modify at least part of the internal flash <br /> memory, say the top 4 KB of the 16F877(A). Basically <br /> this calls for a read and a write instruction. Apart from <br /> these, the run routine from internal EEPROM call should <br /> be extended to also allow running code from the internal <br /> flash memory in the same way, and extend it in such a <br /> way that assembly level routines can be called as well. <br /> Note that the latter would require storing 14-bit values, <br /> and the former only needs 8-bit values. Basically most <br /> of this could be controlled using the 16-bit mode field, <br /> but this might not be transparant to the user.</p></div>Maarten HofmanThu, 13 Oct 2005 17:04:09 -0000https://sourceforge.net909c6824bc40ec0c169f18dd43ec9ae3f4a9c822
