A few test points covering the user interface block have been placed on the AT32UC3L-EK for the verification of important signals.
| Designation | Feature |
|---|---|
| TP1 | Input voltage on the AT32UC3L064 RESET_N pin, depending on the state of the RST pushbutton |
| TP18 | Input voltage for the accelerometer. Should be 1.8V nominal |
| TP15 | Output voltage on the accelerometer VoutZ pin |
| TP16 | Output voltage on the accelerometer VoutY pin |
| TP17 | Output voltage on the accelerometer VoutX pin |
| TP19 | Input voltage on the AT32UC3L064 WAKE_N pin, depending on the state of the WAKE pushbutton |
| TP20 | Voltage level on LED0 |
| TP21 | Voltage level on LED1 |
| TP22 | Voltage level on LED2 |
| TP23 | Voltage level on LED3 |
