1.7.15.6 Smart Card SFRs  
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.

Select Smart Card Interface - These bits select the interface that is using  
the IS0 UART. These bits do not activate the interface. Activation is  
performed by the VccCtl register.

00 = No smart card interface selected.  
01 = External Smart Card Interface selected (using SCLK, SIO).  
1X = Internal Smart Card Interface selected.  
1 = Enabled, 0 = Disabled. When enabled, ISO UART is bypassed and the  
I/O line is controlled via the SCCtl and SCECtl registers.
