EVAL-ADP5020
USING THE SOFTWARE
Before running the software, ensure that the board is plugged
into the computer USB port (the VBATT OKAY, VDDIO
OKAY, and VOBARD OKAY LEDs on the motherboard should
light up).
Install the ADP5020 evaluation software as described in the
Quick Start section. Failure to detect the adapter board prompts
an error message, as shown in Figure 15. If this occurs, check
the connection and restart the program.

VIEW/MODIFY REGISTER SETTINGS
The USER REGISTERS section of the GUI window displays
the ADP5020 register settings (following a Read Registers
operation) and allows you to modify the current values. To
facilitate operation, all the possible device configurations are
listed in the drop-down boxes. You can select the desired value,
then program the device by clicking the Write Registers button.
If the Smart Update check box is selected (default condition),
as soon as a register value is changed, the application sends a
programming command for that specific register without the
need to click the Write Registers button. When the Smart
Update check box is cleared, data is written to the device only
after clicking the Write Registers button.
The Buck 1 Vout Sel. drop-down box allows you to change the
Buck 1 regulator output voltage to one of the following settings:
2.5 V, 2.8 V, 2.9 V, 3.0 V, 3.2 V, 3.3 V, or 3.7 V. The default value
is 3.3 V. This box corresponds to BK1_VSEL, Bits[2:0] in the
BUCK1_VSEL register (Address 0x01).
The Buck 2 Vout Selection drop-down box allows you to change
the Buck 2 regulator output voltage to one of the following
settings: 1.1 V, 1.2 V, 1.3 V, 1.4 V, 1.5 V, 1.6 V, 1.7 V, or 1.8 V.
The default value is 1.2 V. This box corresponds to BK2_VSEL,
Bits[7:4] in the BUCK2_LDO_VSEL register (Address 0x02).
