VTARGET

VTARGET controls the operating voltage for the target board. Through the use of the

slide bar or the text box, this voltage can be regulated between 0 and 6.0V in 0.1V incre-

ments. Please refer to the device datasheet to find the specified voltage range for the

selected device. Both voltages are read by pressing the “Read Voltages” button, and

written by pressing the “Write Voltages” button.

The physical connection of the VTARGET voltage is shown in Figure 3-22 on page 3-16.

5.3.5.2

AREF

AREF controls the analog reference voltage for the ADC converter. This setting only

apply to devices with AD converter. Through the use of the slide bar or the text box, this

voltage can be regulated between 0 and 6.0V in 0.1V increments. Please refer to the

device datasheet to find the valid voltage range for the selected device. Both VTARGET

and AREF are read by pressing the “Read Voltages” button, and written by pressing the

“Write Voltages” button.

It is not possible to set AREF to a higher voltage than VTARGET because this will per-

manently damage the AVR.

The physical connection of the AREF voltage is shown in Figure 3-24 on page 3-18.
