Microcontroller Interface
CS
12
N/A
I
When CS = 1, the control and signal pins are
configured normally. When CS is set low,
CMDVCC%, RSTIN, and CMDVCC#. are
latched. IOUC, AUX1UC, and AUX2UC are
set to high-impedance pull-up mode and do not
pass data to or from the smart card. Signals
RDY and OFF are disabled to prevent a low
output and the internal pull-up resistors are
disconnected.
OFF
32
1
O
Interrupt signal to the processor. Active Low -
Multi-function indicating fault conditions and
card presence. Open drain output configuration
–
It includes an internal 20kΩ pull-up to V
DD.
Pull-up is disabled in Power down state and CS
= 0 modes.
I/OUC
1

IO
System controller data I/O to/from the card.
Includes a pull-up resistor to VDD.
AUX1UC
2
N/A
IO
System controller auxiliary data I/O to/from the
card. Includes a pull-up resistor to VDD.
AUX2UC
3
N/A
IO
System controller auxiliary data I/O to/from the
card. Includes a pull-up resistor to VDD.

I
Logic low on one or both of these pins will
cause the LDO to ramp the Vcc supply to the
smart card and smart card interface to the
value described in the following table
