Note:
The jumper setting does not affect operation for other devices.
ATtiny11 and ATtiny12 also have the possibility to disconnect the external RESET pin
and use it as a general I/O pin (PB5). This is done by setting the jumper marked RST in
position OFF. Jumper RST must always be set in position ON for all other devices.
To use AT90S2333, AT90S4433, AT90S4434, or AT90S8535, the 10-lead cable on the
pod must be mounted. Table 4-2 shows how to connect this cable.
Note:
Connection of the 10-lead cable does not affect operation for other devices.

The ICE10 Power
System
The ICE10 system has an internal power regulator that can deliver 15W at 5V. The
ICE10 itself uses about 10W, so if the user application is powered from the ICE10 sys-
tem, it cannot use more than 5W (i.e. 1A/5V). If this value is exceeded, the ICE10
system may be damaged or not work properly.
The power supply delivered with your ICE10 is dimensioned to meet the requirements of
the emulator. If another power supply is used, it should supply a voltage between 9 and
15 VDC, minimum 20W. The battery eliminator connector on the ICE10 system is a
standard type with 2.1 mm center tap. Center tap is negative.
4.3.1
The Target
Applications Power
Requirements
If the target application should be powered from the ICE10, the jumper named
“EXT.POWER” must be mounted and the jumpers labeled “PW2”, “PW1” and “PW0”
removed.
If the target application has its own power supply, the jumper named “EXT.POWER”
must be removed. The ADCPOD must also be set to convert voltages to the required
voltage level. Use Table 4-3 to find the settings on the jumpers named “PW2”, “PW1”
and “PW0”.
