Hello ! Until now, I was using mc9s12dp256 with ICC12 V6 professionnal, paged programm, and all was ok. Now, using mc9s12xdp512cal, with ICC12 professionnal V6, I need to use XGate processor (communication SCI between 2 MCU). Without XGate, the main S12 CPU would be overload ! I read the Freescale datasheets, specially the chapters about : - XGate, - Memory Mapping Control - Interru...

My module is working as a slave receiver, my I2C ISR can be simplified as follows: void interrupt I2CISR(void) { IBIF = 1; bThisByte = IBDR; } After the last statement, the receiver sends out an ACK, and after this ACK, the MCU holds both SDA a

I've recently been studying M.Doughman's AN2153: Serial Bootloader for MC9S12DP256. It is stated that S-records generated by Cosmic software works fine, but I'm on Metrowerks CodeWarrior, so... I had no problems installing the bootloader into the Protected High area (Starti

Both the MC9S12DP256 and the 68HC58 datasheets talk about the output to the J1850-VPW bus. What about the J1850PWM bus. My guess is that it is just a matter of physical interface between the selected controller and the bus, right? Also, very little information may be found about the actual physical interface that is recommended to the J1850PWM bus. The SAE spec itself only discuss the tim...

Before I commit to a PCB I am looking for a couple of reference designs that work to check my design against !!!! I am using an MC9S12DP256 microcontroller with an AM29F800B (512k byte X 16 bit wide) flash memory chip for external program memory. I want to be able to use the P&am

Hello, I have a Wytec MC9S12DP256 MiniDragon Development board. I have written a simple program that uses the RTI interrupt to update the status of PORTM and the rest of the program waits and sends messages via the serial port (SCI0) to the computer and toggles the ports as necessary.=20=20 The code is fully debugged and works perfectly when using the board in EVB mode with the DBug12 ...

Hello, i use icc12 with CML9S-12DP256 board from Axiom ( MC9S12DP256 MCU). I want to debug with noice debugger but i can't step the source file with it. The program runs until main, and then, when i want to step with NOICE debugger, it doesn't work because the program runs without
