evaluation kit user manual for fx828 and fx829 EV8000 ? 2004 cml microsystems plc 31 um8000/4 notes : a) assembler output files must be in the intel hex format (.hex) in order to be usable by this programming software. b) the pic c supplied has a configuration word which is preset to 3fb9h if it is a pic 16c74jw or 16lc74jw, or to 3fb1h if it is a pic 16c74ajw or 16lc74ajw. in each case, this selects the crystal oscillator, dis ables the watch dog timer, enables the power up timer and disables code protection. the programming software currently defaults to 3fb1h. consult arizona microchip technology for more information on the configuration word. c) the "blank check" command (b) only looks at the first location. a programmed device will always have data in this location as it is the program start address. d) for each of the commands b,p,r and v the user will be prompted to manually reset the target c, by pressing the re set switch (sw1) on the c board. this is because pic programming always starts from location 0000 and the program counter can only be incremented. e) pressing a will display the program data in the bo ttom window, formatted in pages of 48 consecutive locations. use the and keys to scroll through the data. pressing will return the user to the >ok prompt. 1.6.4.2 ef8000 firmware the pic c is supplied pre-programmed with ef8000 firmware, which is used to convert the rs232 serial interface into a c-bus interface. it also executes some of the higher data rate commands and collects high speed interrupts for pre-processing, before passing these back to the pc. its operation is transparent and it is controlled by the es8000 windows application software. 1.6.5 known bugs in the es8000 (version 1.0) software the warnings highlighted in sections 1.6.3. 20 and 1.6.3.22 should be followed to prevent any windows application failures.
