How to output 32K crystal signal to specific pin on LAUNCHXL-CC2640R2

The following steps show you how to output 32K crystal signal to specific pin on LAUNCHXL-CC2640R2 using simple_peripheral example.

1. Add " #include  < driverlib/aon_ioc.h > " in simple_peripheral.c.

2. Add the following two lines in the end of SimplePeripheral_init() to output 32K crystal signal to DIO_10.

    IOCPortConfigureSet(IOID_10, IOC_PORT_AON_CLK32K, IOC_STD_OUTPUT);
    AONIOC32kHzOutputEnable();

3. Use scope to check wave form and frequency on DIO_10.
