11
AUX1: Auxiliary data signal to/from card. Includes a pull-up resistor to VCC.
AUX2
12

10
AUX2: Auxiliary data signal to/from card. Includes a pull-up resistor to VCC.
RST
16

14
Card reset: provides reset (RST) signal to card.
CLK
15
7
13
Card clock: provides clock signal (CLK) to card. The rate of this clock is determined by
the external crystal frequency or frequency of the external clock signal applied on
XTALIN and CLKDIV selections.
PRES

7
Card Presence switch: active high indicates card is present. Should be tied to GND
when not used, but it Includes a high-impedance pull-down current source.
PRES

6
Card Presence switch: active low indicates card is present. Should be tied to VDD when
not used, but it Includes a high-impedance pull-up current source.
VCC

15
Card power supply – logically controlled by sequencer, output of LDO regulator.
Requires an external filter capacitor to the card GND
