HL7692 - CTS / RTS with PIC32

Hi to all,

I’m connecting HL7692 with PIC microcontroller (PIC32MX440F512H).
How to correctly connect CTS and RTS UART pin with PIC ? From PIC documentation it is possibile to choose between 2 different
configurations “Simplex Mode” and “Flow Control Mode”, which one I have to use with HL7692 (and AT&K3) ?

Here the PIC UART reference ww1.microchip.com/downloads/en/D … 61107G.pdf

Best regards
