General Description

3.3 POD Bay
The ICE50 has a very flexible architecture that will ensure a long product life. The differ-
ent AVR devices are characterised through their number of I/O pins and analog
features. Both the I/O pins and the analog features are implemented on the POD board.
If new AVR devices are made available to the market that contain I/O or analog features
that cannot be emulated by the current POD, Atmel is dedicated to create new POD
modules that support the functionality of the new devices.
3.3.1 Removing POD from
POD Bay If for some reason the POD must be removed from the POD Bay, the recommended
procedure is as described below. See also Figure 3-4.
1. Lift the POD on the front edge until a click is heard. The POD is now ready to be
pulled up from the bay.
2. Lift the POD out of the Bay.
Figure 3-4. Removing POD from POD Bay
Without the POD connected, the ICE50 will still be able to emulate core functions of the
AVR (e.g., timers). This feature can be useful in some debugging sessions. If the POD is
inserted and there is no target power applied, the ICE will be held in Reset until target
power is turned on. By disabling POR and BOD Reset in ICE50 other options dialog,
ICE50 will emulate correctly even if target power is not connected.
3.3.2 Inserting POD Into
POD Bay Only original ICE50 Pods should be used with ICE50 and care should be taken when
placing or removing the POD. During normal use there is no need to remove the POD
from the bay. If for some reason the POD is disconnected, the recommended procedure
to re-insert the POD is as follows. See also Figure 3-5.
1. Place the POD in the ICE50 POD connector. Make sure that the connector male
and female guides align.
2. Use both hands and apply pressure on the upper half of the POD (on top of the
connector).
3. After pressing the connector firmly in place, use one hand to apply pressure on
the lower half of the POD. You will hear a click when the POD locks into position.
