Pin Name Description49 SIMCLK Clock signal for the SIM card, generated by the Nokia12 module. For more information on the SIMinterface, see Chapter 4.5.50 SIMDATA Data line between the SIM card and the Nokia 12module. For more information on the SIM interface,see Chapter 4.5.51 SIMDET SIM card detection signal. For more information onthe SIM interface, see Chapter 4.5.52 IO VOLTAGE This pin sets logic level for the application. Voltagemust be 1.8 V - 5.0 V. For more information on thepower supply, see Chapter 4.3.53 OUTPUT1 /PORT3RXDigital output from the Nokia 12 module. Logic level isset by the IO VOLTAGE pin (pin 52). If PORT3 isconfigured for serial communication, this is a receive(input) signal.54 INPUT4 /PORT3TXNote! Direction changes if pin 53 is configured forserial communication.Digital input to the Nokia 12 module. Logic level is setby the IO VOLTAGE pin (pin 52).
