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.

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.
GND
