In the Source window, insert a breakpoint at the “PTT = ATDDR0H;” instruction in the main function.

  • Page 20: Hardware Features

    Contrariwise to traditional in-circuit emulation (where the target application is executed and emulated inside the emulator), PK-HCS12E128 uses the very same target microcontroller to carry on in-circuit execution. This means that all microcontroller’s peripherals (timers, A/D converters, I/O pins, etc.) are not reconstructed or simulated by an external device, but are...

  • Page 30: Stop Assembly Instruction

    PK-HCS12E128 User's Manual STOP Assembly Instruction The BDM peripheral doesn’t work in STOP mode. If, on the Condition Code Register (CCR), the S bit is set, the STOP instruction will stop all the microcontroller’s activities (and therefore the BDM peripheral). If, on the other hand, the S bit is reset, the STOP instruction will be executed as two NOP instructions.

    4. Debugging Features PK-HCS12E128 always sets the CLKSW bit to 0: you are therefore free to change the microcontroller’s bus frequency through the PLL, since this will not affect the BDM communication. Note: PK-HCS12E128 uses the 16 MHz external oscillator as the clock source for the BDM communication.

    § Serial numbering. Note: due to the evaluation purposes of the PK-HCS12E128 starter kit (and therefore to the slow data transfer rate from the PC to the target and vice versa), the DataBlaze programming utility takes a long time to write to/read from the whole microcontroller memory.
