2.9.1 Device and Package Selection
User has to select the desired device and package. The selection will determine the mapping window
setting. The package selection will also determine the type of graphical display in the pinview window.
2.9.2 Operating Mode Selection
There are five mode selections:
•
Mode 4
•
Mode 5
•
Mode 6 [Default]
•
Mode 7
•
Target Mode
NOTE: For ROMless mode operation, user has to make sure that external memory is connected before
any emulation can occur. If user's target system is not ready, user may map the area to the optional
SODIMM memory for temporary usage.
2.9.3 Clock Selection
User can choose from two different sources: Internal or External Target Clock.
For internal clock, user can key in any frequency from 1MHz to 25MHz, in the step of 100KHz (in
Options->Emulator->Systems ...). The emulator will generate the requested clock for the running
processor.
For external target clock, user can either input an oscillating clock into the EXTAL pin, or place a crystal
at the actual footprint user cable (EXTAL and XTAL pins).
2.9.4 User Signal Masking Control (RESET, NMI & STBY)
These signals can be masked by the emulator when user executes the programs. At startup, the RESET
and NMI signals are not masked, whereas STBY signal is masked (in Options->Emulator->Systems ...).
Illegal access break can also be enabled in this dialog.
NOTE: If STBY signal is asserted during user run mode, the emulator will enter standby mode, and the
emulator control registers are initialised.
2.9.5 Downloading of Emulation Function (Programmable Function Generator)
User has to download the selected function to the Programmable Function Generator before it can be
used. This has to be done once the emulator is switched off.
Please refer to section 3 for more details.
