I was able to set clock signal in all the DIOs except DIO_16 and DIO_17.
====================== CC2640R2_LAUNCHXL.c =================================
const PIN_Config BoardGpioInitTable[] = {
CC2640R2_LAUNCHXL_PIN_RLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX, /* LED initially off */

CC2640R2_LAUNCHXL_PIN_BTN2 | PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_BOTHEDGES | PIN_HYSTERESIS, /* Button is active low */
CC2640R2_LAUNCHXL_SPI_FLASH_CS | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH | PIN_PUSHPULL | PIN_DRVSTR_MIN, /* External flash chip select */

};
====================== CC2640R2_LAUNCHXL.h =================================
/* SPI Board */
#define CC2640R2_LAUNCHXL_SPI0_MISO IOID_10 /* RF1.20 */
#define CC2640R2_LAUNCHXL_SPI0_MOSI IOID_9 /* RF1.18 */
#define CC2640R2_LAUNCHXL_SPI0_CLK IOID_17//8 /* RF1.16 */
#define CC2640R2_LAUNCHXL_SPI0_CSN PIN_UNASSIGNED
This is the code that i am using.
