1. FRONT TECICE HC11 CIRCUIT BOARD PAR TECE Engineers Collaborative Inc Page 23 TECICE HC11 USER S MANUAL For example if we had 2 jumpers in place as shown at 2000 3FFF and C000 DFFF then the 8K byte memory segments from 2000 to 3FFF and from C000 to DFFF would be external on the target system and all other memory would be internal to the emulator This means that all memory writes would go to both internal and target system memory but memory reads to locations 2000 3FFF and C000 SDFFF would be from the target system while all other reads would come from internal emulator memory 8000 9FFF 1EFF 2000 3FFF 1 JUMP FOR TARGET MEM 3 5 5 Changing Emulator Probes Currently two types of emulation probes are supported by TECICE HCI1 they are 1 52 PIN PLCC and 2 48 PIN DIP To change an emulation probe just remove one probe adapter and replace it with the other probe adapter 52 PIN PLCC EMULATION PROBE This probe consists of two 26 conductor ribbon cables with connectors on one end that attaches to JP1 or JP2 the longer cable and JP3 or JP4 the shorter cable on the emulator board On the target system end of these cables there are connectors that attach to 52 PIN PLCC EMULATION PROBE adapter that in turn plugs into a 52 pin plcc socket on the target system2. Engineers Collaborative Inc Page 16 TECICE HC11 USER S MANUAL 3 3 LIMITATIONS In some ways the emulator will not behave exactly like the 68HC11 microcontroller chip that is being emulated The user must be aware of these differences and allow for them No memory limitation checking is done to assure that the user program will fit in the amount of RAM ROM space available in the device being emulated The user must know the memory map of the device being emulated and make sure that only valid RAM ROM memory locations are used The TECICE operates in the expanded mode see schematic diagram sheet 3 If the user writes to x03C to put into single chip mode the TECICE will need to be reset The IRQ and XIRQ pins have an internal pull up resistor on each pin to keep false interrupts from occurring when the pod is not connected to a target system Breakpoints are implemented by forcing an SWI to occur This causes several limitations 1 The SWI puts nine bytes on the user s stack Space must be available on the stack 2 All programs must set the Stack Pointer otherwise the TECICE won t get valid data off the stack The Stack Pointer will default to SFF or F13D on the TECICE 3 Only software breakpoints may be used to break any code that is written in the internal RAM There is no way to force an SWI onto the bus when the opcode is being read from internal memory This doesn t effect breaks on reads or writes Because of this limit

8. 48 PIN DIP EMULATION PROBE You can change from a 52 pin plcc probe to a 48 pin dip probe by changing the adapter on the target system end of the two 26 conductor ribbon cables without opening the emulator housing The 48 pin dip probe consists of the same two 26 conductor ribbon cables as the 52 pin plcc probe and they attach to the emulator board at the same points Only the adapter is different PAR TECE Engineers Collaborative Inc Page 24 TECICE HC11 USER S MANUAL 3 5 6 Changing The Clock Frequency Changing the clock frequency usually consists of setting the clock freq selector switch to the desired divider value The TECICE HC11 is shipped from the factory with an 8 Mhz oscillator installed in the X2 socket on the board X2 may be changed by the user to obtain other clock rate as shown in the chart below Clock FIGURE 4 CLOCK FREQUENCY SELECTOR SWITCH The clock frequency selector switch is a ten position rotary switch which selects the emulation processor clock rate To select a given clock rate find the desired rate in the chart below and rotate the switch until the desired number is next to the alignment dot Note that X2 is the clock oscillator that is located in the upper left hand corner of the board As shipped from the TECI factory X2 is an 8 0 Mhz oscillator from which the clock rates shown in the second column of the chart are derived X2 is a standard type of clock oscillator that can be obtained in many
