Chapter 4:Connecting the Emulator to a Target System
Instructions for aligning and plugging in a clock module are given on page 27.
Once the correct clock module has been installed, skip ahead to "Running the
emulator configured like the processor" (page 67). If you have problems getting
the clock to operate correctly, return to this section and review the additional
information below.
Clock module information
•
If the target system uses an external oscillator
– Use the Target Oscillator Clock Module (64780-66509) that was
installed in the emulator probe at the factory.
– MODCK0=1, driven by emulator.
– MODCK1=0, driven by emulator.
– You can run PV to verify operation of the emulator connected to a
target system using an external oscillator. See page 111 for details.
•
If the target system uses an external crystal
– Plug in Module B, Target Crystal Clock Module.
– MODCK0=value driven by target, or '1' if driven by emulator default.
– MODCK1=0, driven by emulator.
– Do not run PV. PV will fail with Module B installed.
•
If the target system runs with 4.194-MHz clock rate
– Plug in Module C, 4.194 MHz Clock Module.
– MODCK0=0, driven by emulator.
– MODCK1=1, driven by emulator.
– You can run PV to verify operation of the emulator connected to a
target system running at 4.194 MHz. See page 111 for details.
•
If the target system runs with 32.768-MHz clock rate
– Plug in Module E, 32.768 kHz Clock Module.
– MODCK0=1, driven by emulator.
– MODCK1=1, driven by emulator.
– You can run PV to verify operation of the emulator connected to a
target system running at 32.768 MHz. See page 111 for details.
•
If you wish to run emulator PV to test all modes of operation
– Plug in Module A, Test Clock Module.
– Do not use Module A when running any emulation session. Module A
is for running PV only. See page 111 for details.
