4.20 Smart Card Interface, SCI
The PrimeCell Smart Card Interface (SCI) is an AMBA compliant SoC peripheral that
is developed, tested, and licensed by ARM Limited.
The following key parameters are programmable:
• Smart Card clock frequency and communication baud rate
• protocol convention
• card activation and deactivation time
• check for maximum time for first character of Answer To Reset (ATR) reception
• check for maximum duration of ATR character stream
• check for maximum time for receipt of first character of data stream
• check for maximum time allowed between characters
• character and block guard time
• transmit and receive character retry and FIFO level
• clock start and stop time and inactive level.
See the self-test software that is supplied on the CD accompanying the PB926EJ-S for
a example of detecting a SIM card response to a reset.
