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.

System interface supply voltage and supply voltage for internal

circuitry.

LDO regulator power supply source.

Test pin. Should be tied to GND.

Digital ground.
