The Asynchronous Timers in the emulated part may be clocked by an external 32 kHz
crystal. This crystal should be connected to the TOSC1 and TOSC2 pins of the person-
ality adapter. To ensure proper operation the crystal should be connected as close to
the personality adapter as possible. The Oscillator driver on the probe is designed to
work with most parallel mode 32 kHz crystals.
In AVR Studio the Emulator may be set to run on an Internal RC Oscillator. See section
device selection for a description of how to set up the Internal RC Oscillator.
External crystal/resonator is not supported on the ICE50 probe. Instead, configure the
Emulator to use the internal programmable clock. The XTAL1 pin will then be tri-stated.
XTAL2 pin will be enabled and the internal programmable clock is driven out on the
XTAL2 pin. See special section for a description of how to set up the XTAL2 clock.
External RC Oscillator is not supported on the ICE50 probe. Instead, configure the emu-
lator to use the internal programmable clock. The XTAL1 and XTAL2 pins will then be
tristated.
ICE50 is supplied with a Test Adapter. See Figure 3-26.

Note:
The adapter includes an identification code that the ICE50 and AVR Studio uses for
detection. The ICE50 Test Adapter is used for the following tests:
