1.7.13.6 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 73S8010x parts to generate the ISO 7816-3
compatible signals and sequences. Multiple 73S8010x devices can be connected to the external smart
card interface.

SCSel.4
SCSel.3
SELSC.1
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.
SCSel.2
SELSC.0
SCSel.1
BYPASS
1 = Enabled, 0 = Disabled. When enabled, ISO UART is
bypassed and the I/O line is controlled via the SCCtl and SCECtl
registers.
