Chapter 5: Connecting and Configuring the Emulator
Configuring the Emulator
Processor clock speed configuration
Use the cf dprocck command to display the default clock speed.
To set the default clock rate if the processor
clock rate is less than 8 MHz
If a target system’s processor clock rate is less than 8 MHz following
powerup, the default clock rate must be set to 131 kHz.
This can occur when the target system has the processor running off of
an external clock source that is less than 8 MHz or is using the clock
synthesizer with a crystal that is lower in frequency that the standard
crystal.
The actual processor clock rate should then be communicated to the
emulator through the configuration processor clock rate entry. The
emulator will then start communications with the target processor at
