CCS/MSP430FR6989: MSP430FR6989 RTC pin multiplexing

Part Number:MSP430FR6989

Tool/software: Code Composer Studio

Dear TI team,

I've noticed that in the out-of-the-box example for the MSP430FR6989 launchpad the pin multiplexing (for the 32.768 kHz oscillator) is done this way:

    GPIO_setAsPeripheralModuleFunctionInputPin(
           GPIO_PORT_PJ,
           GPIO_PIN4 + GPIO_PIN5,
           GPIO_PRIMARY_MODULE_FUNCTION
           );

but when I open the datasheet (rev. B) I notice the following:

To me from the datasheet it looks like the PJ4 should have SECONDARY module function and PJ5 should have TERNARY.

Any ideas what I'm getting wrong?

Regards
