Smart Card SFRs
Smart Card Select Register (SCSel): 0xFE00
0x00
Table 80: The SCSel Register
MSB
LSB
SELSC.1 SELSC.0 BYPASS
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.6
SCSel.5
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.
