Figure 4-1. Component Placement of AT90ADCPOD
The AT90ADCPOD contains the following functions:
Analog comparator
Clock circuits for handling of the timer oscillator and XTAL signals from the target
application
Analog to digital converter
Bus switches for converting the voltage on the I/O signals
11 jumpers and one switch must be set on AT90ADCPOD to configure it for desired
operation.
4.2 Configuring the
AT90ADCPOD
AT90ADCPOD is connected to the ICE10 unit using the pod cable (the wide cable) and
to the user application using the 8-pin, 20-pin, 28-pin, or 40-pin probe.
Note: It is important that the probe cable is correctly connected to the user application.
Only one probe cable should be connected. The colored wire of the probe cable
indicates pin 1 of the AVR device.
Use the appropriate probe cable and connect the application to the connector labeled
with the correct part number. Please note that the ICE10 may be damaged if the probe
cable is connected to the wrong connector.
The 8-pin AVR devices have multiple options for using port pins PB3, PB4 and PB5.
Please refer to data sheets for detailed information. To select how PB3 and PB4 should
be used, the jumpers labeled PB3 and PB4 must be set correctly. Table 4-1 shows the
settings for these jumpers.
