ous configuration pins during the configuration process. The
configuration interface is designed primarily for 2.5V opera-
tion when the VCCO_2 (and VCCO_1 in BPI mode) con-
nects to 2.5V.
The configuration pins also operate at other voltages by set-
ting VCCO_2 (and VCCO_1 in BPI mode) to either 3.3V or
1.8V. The change on the VCCO supply also changes the I/O
