Smart Card Select Register (SCSel): 0xFE00  0x00
The Smart Card Select register is used to determine which smart card interface is using the ISO UART.
The internal Smart Card has integrated 7816-3 compliant sequencer circuitry to drive an external smart
card interface. The external smart card interface relies on 73S8010 parts to generate the ISO 7816-3
compatible signals and sequences. Multiple 73S8010 devices can be connected to the external smart
card interface.
