Crystal oscillator input: can either be connected to crystal or

driven as a source for the card clock.

Crystal oscillator output: connected to crystal. Left open if

XTALIN is being used as external clock input.

VDD fault threshold adjustment input: this pin can be used to

adjust the VDDF value (that controls deactivation of the card).

Must be left open if unused.
