(By seting Last_TXByte and

RX mode will start after last
TX byte)
WWT is set by the value in the BWT registers.

1.7.13.4 Bypass Mode
It is possible to bypass the smart card UART in order for the firmware to support non-T=0/T=1 smart cards.
This is called Bypass mode. In this mode the embedded firmware will communicate directly with the
selected smart card and drive I/O during transmit and read I/O during receive in order to communicate with
the smart card. In this mode, ATR processing is under firmware control. The firmware must sequence the
interface signals as required. Firmware must perform TS processing, parity checking, break generation and
CRC/LRC calculation (if required).
1.7.13.5 Synchronous Operation Mode
The 73S1209F supports synchronous operation. When sync mode is selected for either interface, the CLK
signal is generated by the ETU counter. The values in FDReg, SCCLK, and SCECLK must be set to obtain
the desired sync CLK rate. There is only one ETU counter and therefore, in sync mode, the interface must
