I/O
DESCRIPTION
I Smart Card card detect. This input is asserted when Smart Cards are inserted.
O Smart Card clock. The controller drives a 4-MHz clock to the Smart Card interface when enabled.
I/O Smart Card data input/output
I
Smart Card function code. The controller does not support synchronous Smart Cards as
specified in ISO/IEC 7816-10, and this terminal is in a high-impedance state.
I/O
Smart Card general-purpose I/O terminals. These signals can be controlled by firmware and are
used as control signals for an external Smart Card interface chip or level shifter.
I Smart Card overcurrent. This input comes from the Smart Card power switch.
O Smart Card power control for Smart Card socket.
I Smart Card reserved. This terminal is in a high-impedance state.
O
Smart Card reset. This signal starts and stops the Smart Card reset sequence. The controller
asserts this reset when requested by the host.
