NOTES:
1) VDD = 2.7V to 5.5V DC.*
2) VPC = 4.75V(ISO)/4.85V(NDS) to 5.5V DC*
3) Required if external clock from uP is used.
4) Required if crystal is used.
5) R1 and R3 are external resistors that adjust the VDD
* Do not begin a NDS card session until VPC > 4.85V and VDD > VTH (VDD fault threshold)
Y1, C2 and C3 must be removed if external clock is used.
