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.
