Figure 4-5. Supply Voltage Parameter for Externally Regulated Mode
Populating R84 shorts the VCCD and VDD pin of CY8CMBR3116 for the externally regulated mode.
Populating R85 ensures that the board is always powered at 1.8 V. This overrides the power settings
done from the EZ-Click customizer tool (see

Note: Do not configure the device with the Supply Voltage (V) parameter set to 1.8±5%, before
populating resistors R84 and R85. If you do so, the EZ-Click customizer tool will throw an error, as
shown in
