Chapter 6: Connecting and Configuring the Emulation Module
Configuring the Emulation Module
will allow display and modification from the user interface. For
example, when 68332 is selected as the processor type, the interface
will support direct access to the SIM, the QSM, the TPU, and the
TPURAM registers.
The emulator does not have explicit support for all CPU32 processors.
When using a member of the CPU32 family that is not explicitly
supported it may be possible to select a processor that is a formal
subset of the unsupported processor. This will provide direct access to
all of the internal memory mapped registers that are common. Since
the registers in the internal modules are memory mapped, registers in
unsupported CPU32 processors are also accessible through the
memory commands. For example, on a 68332, SIM registers can be
accessed at memory locations 7FFA00 to 7FFA7F or FFFA00 to
FFFA7F.
To configure the processor clock speed (BDM
communication speed)
The maximum communication rate with the target processor through
the BDM port is based upon the target processor type and the target
processor clock speed.
For best performance, set the processor clock speed to the highest
speed that is equal to or less than the clock speed of the target
processor. You may set the processor clock speed to a speed lower than
the actual clock speed of your target system. Use the 25 MHz option for
microcontrollers running faster than 25 MHz.
If using the internal clock synthesizer, set the EMSYNCR (EMulator
copy of the SYNthesizer Control Register, SYNCR) to the same value as
set by the initialization code. See Chapter 7, "Using Internal Registers
(SIM and EMSIM Registers)," beginning on page 159.
