Chip Selection
The CS pin allows multiple circuits to operate in parallel, driven from the same host control bus. When
CS is high, the pins RSTIN, CMDVCC% , CMDVCC# and CLKIN control the chip as described. The pins
I/OUC, AUX1UC, and AUX2UC have 11 k ? pull-up resistors and operate to transfer data to the smart
card via I/O, AUX1, and AUX2 when the smart card is activated. The signals OFF and RDY have 20 k ?
pull-up resistors.
When CS goes low, the states of the pins RSTIN, CMDVCC% , CMDVCC , and CLKIN are latched and held
internally. The pull-up for pins I/OUC, AUX1UC, and AUX2UC become a very weak pull-up of
approximately 3 μ A. No transfer of data is possible between I/OUC, AUX1UC, AUX2UC and the
smart-card signals I/O, AUX1, and AUX2. The signals OFF and RDY are set to high impedance and the
internal pull-up resistors of 20 k ? are disconnected. With regard to de-activation, CS does not affect the
operation of the fault sensing circuits and card sense input.
