Posted on May 17, 2011 at 13:13Hi: The limitation may come from the internal design of the SPI module, as it might require 2 or 4 peripheral clock cycles to read the data correctly. 18MHz it still good, as other SPI modules in other MCUs have even l...
Posted on May 17, 2011 at 13:12Hi: It would be useful to indicate what it is the actual problem: cannot program the MCU? Code doesn't run? Timer doesn't run? Have you tried the debugger and step through the code? A quick look at you code reveals a p...
Posted on May 17, 2011 at 13:10Hi: Have you tried running the JTAG a a lower clock frequency (100KHz or less)? JTAG performance is somewhat dependent of the PCB layout, and one board might run at a higher JTAG clock than other. There is also the opt...
Posted on May 17, 2011 at 13:04Hi: What would be the problem of using the Flash Memory? The parts have endurance of 10000 erase/write cycles. You can debug from RAM (if that is what you need to do) as well, by placing your code in RAM and executing ...
