Hi,

reading device datasheet strictly, operation isn't guaranteed for nominal VCCIO below 1.2 V (1.14 min.).

In so far seeing the device operating correctly in your test proves nothing, particularly not operation over full temperature range or for devices with marginal parameters.

Regarding risk, at least I won't expect damage with VCCIO below specified range.
