Hi every one,
we want to try lpc11u68 for contacting with a ISO7816 based smart Card.
As you know this required using usart0 peripheral in iso7816 mode,Also clock pulses(CLK pins) must be generated separately(maybe using (SCTimer/PWM).
Does any one know whats maximum frequency SCTimer can generate?
I think for transitiving in 115200 baud-rate we need 42.96 MHZ of clock frequency, Can SCTimer toggle a pin with this frequency?
As a other way Can we set Fi & Di parameters of ATR in any bigger value than 372 for transferring more data in the same clock frequency?
