8.3 Debugging Without DVIO

It is safe and possible to have only DVCC and not DVIO connected to the device for the purpose of simple device debugging. However, DVIO pins and their related functions are not available in this mode. Additional effects include higher leakage current during debug; therefore, this option is suitable only for preliminary debugging of the device.
