Figure 3-25. External Clock
The current version of the Probe has some restrictions with regards to clock options
support. The unsupported clock modes are quite easy to emulate with simple
workarounds as described in Section 3.7.6 and Section 3.7.7. The Probe version can be
found on top of the back side of the Probe (left side of the right picture above).
Version A9902.3.1200.E of the Probe supports the following clock options:
The following clock options are not supported by Probe version A9902.3.1200.C. A
description for workarounds for the unsupported clock modes can be found in section
“External Crystal and External Resonator” on page 19 and “External RC Oscillator” on
page 19.
An external clock signal can be applied to the XTAL1 pin on the emulator probe. The
Emulator can then be set up to use this signal as the system clock. See device selection
for a description of how to set up AVR Studio for this option. The clock signal must meet
the conditions as shown in Table 3-7.
Table 3-7. Clock Signal Conditions
The Emulator may be set up to run on an internal programmable clock. The frequency
range of this programmable clock is 5 kHz to 20 MHz. However, the maximum fre-
quency cannot be set higher than the speed limit of the actual part. Only certain output
frequencies are possible to generate with highest accuracy. However the clock genera-
tor generally produces an output frequency within 0.1% of the desired output frequency.
If the target application should run on the same clock as the AVR chip/emulator, the
internal programmable clock may be driven out on the XTAL2 pin. See section device
selection for a description of how to set up the internal programmable clock.
