Description
This field indicates the IO routing between the host and the Smart Card Interfaces when activated,
seeTable 38 and IODISn value (n=1, 2, 3, 4, 5). When no host IO is routed to a smart card pin, this pin is
driven according to the Interface register. See Section “CIO, CC4, CC8 controller”, page 15.
