CC2640: 5XD CTS/RTS Pin

Part Number: CC2640


Hi Expert,

Do we support RTS/CTS in CC2640 5XD version? I found the UART_RTS/CTS pins in CC2640R2DK_5XD.h are unassigned. 

Which IOID could I SET?

/* UART Board */
#define CC2640R2DK_5XD_UART_RX IOID_1 /* P1.7 */
#define CC2640R2DK_5XD_UART_TX IOID_0 /* P1.9 */
#define CC2640R2DK_5XD_UART_CTS PIN_UNASSIGNED
#define CC2640R2DK_5XD_UART_RTS PIN_UNASSIGNED

Best Regards,

Seamus
