LMK04828: SPI: how to use? pin 5: reset/GPO/SDO?

Part Number: LMK04828

Hi There,

How do I properly connect my SPI master to an LMK04282 chip?

In the EVM's the pinouts used are

SDIO->Pin20,

SCK->Pin19

CS->Pin18

SDO->Pin 5, Reset/GPO.

Why is the read-back SPI line the reset pin? Searching "GPO" on the datasheet doesn't reveal any further information about what that three-letter-acronym means. Am I okay to use a standard SPI interface on this device with the pinouts mentioned above? As it currently stands, I'm concerned that writing any data to the chip will simply reset the device.

Thanks,
