NAME

R/W

DESCRIPTION

INTERFACE_ENABLE

R/W

If the interface is not enabled, the interface pins are tri-stated.

INF_IDLE_CTL_EN

R/W

Enable automatic control of interface idle condition.

Setting this bit will automatically drives SCx_CLK, SCx_RST_N,

SCx_C4, SCx_C8 pins to logic LOW and SCx_IO pin to a value

programmed in INF_IDLE_IO_VAL bit when INTERFACE_ENABLE=0.

When INTERFACE_ENABLE=1 all IOs are controlled by the SCC,

where the state of the SYNC_MODE_SEL does not matter.

Reserved

Always read as 0

INF_IDLE_IO_VAL

R/W

This bit indicates the value to be driven on the SCx_IO line when

INF_IDLE_CTL_EN bit is set.

This bit is available in SEC1110/SEC1210

SC1_SC_FIFO_DIS

R/W

This bit indicates if Smart Card 1 is using the SC_FIFO.

0: SC1 using SC_FIFO

1: In SEC1210, SC2 is using SC_FIFO. In SEC1110 this bit is a don’t

care.

SC_SLOW_CLK

R/W

Must be set when SCx_CLK is running under 10 MHz.

This bit is not used in the SEC1110/SEC1210 parts.

SC_MODE

R/W

Forces the pads into a low current Smart Card Mode with increased

hysteresis. This applies to all Smart Card pins except SC_CLK.

This bit is not used in the SEC1110/SEC1210 parts.

SYNC_MODE_SEL

R/W

Setting this bit put the Smart Card interface into the synchronous

Mode.
