Data from Card -end of ATR
Data from TX FIFO
RLength
Count MAX
1. Interrupt generated when Rlength counter is MAX.
2. Read and clear Interrupt.
3. Set CLK Stop and CLK Stop level high in Interrupt routine.
4. Set TX/RX Bit to TX mode.
5. Reload Rlength Counter.
6. Set IO Bit low and IODir = Output. Since Rlen=(MAX or 0) and TX/RX =1, IO pin is controlled by IO bit.
7. Clear CLK Stop and CLK Stop level.
Note: Data in TX fifo should not be Empty here.
START Bit
Synchronous Clock Start/Stop Mode style Start bit procedure. This procedure should be used to
generate the start bit insertion in Synchronous mode for Synchronous Clock Start/Stop Mode protocol.

RLength Count MAX
1. Interrupt generated when Rlength counter is MAX.
2. Read and clear Interrupt.
3. Set CLK Stop and CLK Stop level high.
4. Set IO Bit low and IODir = Output.
5. Set TX/RX Bit to TX mode.
6. Reload Rlength Counter.
7. Set IO Bit High and IODir = Output.
8. Clear CLK Stop and CLK Stop level.
Note: Data in TX fifo should not be Empty here.
STOP Bit
TX/RX mode
Synchronous Clock Start/Stop Mode Stop bit procedure. This procedure should be used to
generate the Stop bit in Synchronous Mode. SYCKST is bit 7 of STXCTL register.
