int main()

{

SystemInit();



SysCtrl_PeripheralClockCmd(CLOCK_PERIPH_GPIO, ENABLE);

SysCtrl_PeripheralClockCmd(CLOCK_PERIPH_SYS_CONTROL, ENABLE);



GPIO_InitType GPIO_structInit;



GPIO_structInit.GPIO_Pin = GPIO_Pin_9;

GPIO_structInit.GPIO_Mode = Serial2_Mode;

GPIO_structInit.GPIO_HighPwr = ENABLE;

GPIO_structInit.GPIO_Pull = DISABLE;

GPIO_Init(&GPIO_structInit);

return 0;

}

i am trying to get external high speed crystal output(XO16/32M) on GPIO pin of BLE uC,
For this BLUENRG248 GPIO_PIN_9 initialize in Serial2_mode as given in datasheet page no 93.
