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.
V_DD fault threshold adjustment input: this pin can be used to
adjust the V_DDF value (that controls deactivation of the card).
Must be left open if unused.
System interface supply voltage and supply voltage for internal
circuitry.
LDO regulator power supply source.
Test pin. Should be tied to GND.
Digital ground.
