1.7.15 Smart Card Interface Function
The 73S1210F integrates one ISO-7816 (T=0, T=1) UART, one complete ICC electrical interface as well
as an external smart card interface to allow multiple smart cards to be connected using the Teridian 8010
family of interface devices. Figure 14 shows the simplified block diagram of the card circuitry (UART +
interfaces), with detail of dedicated XRAM registers.
Card interrupts are managed through two dedicated registers:
interrupt is enabled) and
interrupt, that can be a card insertion / removal, card power fault, or a transmission (TX) or reception (RX)
event / fault. It should be noted that even when card clock is disabled, an ICC interrupt can be generated
