Figure 18: Smart Card CLK and ETU Generation
There are two, two-byte FIFOs that are used to buffer transmit and receive data. During a T=0 processing,
if a parity error is detected by the 73S1210F during message reception, an error signal (BREAK) will be
generated to the smart card. The byte received will be discarded and the firmware notified of the error.
Break generation and receive byte dropping can be disabled under firmware control. During the
transmission of a byte, if an error signal (BREAK) is detected, the last byte is retransmitted again and the
firmware notified. Retransmission can be disabled by firmware. When a correct byte is received, an
interrupt is generated to the firmware, which then reads the byte from the receive FIFO. Receive overruns
are detected by the hardware and reported via an interrupt. During transmission of a message, the
firmware will write bytes into the transmit FIFO. The hardware will send them to the smart card. When the
last byte of a message has been written, the firmware will need to set the LASTTX bit in the STXCtl SFR.
This will cause the hardware to insert the CRC/LRC if in a T=1 protocol mode. CRC/LRC
generation/checking is only provided during T=1 processing. Firmware will need to instruct the smart
function to go into receive mode after this last transmit data byte if it expects a response from the smart
card. At the end of the smart card response, the firmware will put the interface back into transmit mode if
appropriate.
The hardware can check for the following card-related timeouts:
Character Waiting Time (CWT)
Block Waiting Time (BWT)
Initial Waiting Time (IWT)
The firmware will load the Wait Time with the appropriate value for the operating mode at the appropriate
time. Figure 19 shows the guard, block, wait and ATR time definitions. If a timeout occurs, an interrupt
will be generated and the firmware can take appropriate recovery steps. Support is provided for adding
additional guard times between characters using the Extra Guard Time register (EGT), and between the
last byte received by the 73S1210F and the first byte transmitted by the 73S1210F using the Block Guard
Time register (BGT). Other than the protocol checks described above, the firmware is responsible for all
protocol checking and error recovery.
