RS485 half-duplex SET GPIO to hardware flow control

Hi all,
I'm currently using, MQX 4.0, PXS2010 and RS-485 transceiver (SP485EE). (my board, not the tower)

I'm using the example rs485.c with hardware flow control:

rs485_dev = fopen (RS485_CHANNEL, (const char *) IO_SERIAL_HW_485_FLOW_CONTROL);
  

twr-pxs2010 connects GPIO[51] -> DE, GPIO [12] -> RE.

my board     connects GPIO[98] -> DE, GPIO [99] -> RE.

My question is how to change these pins in the MQX, to work with DE / RE automatically?

Thanks in advance,
Eddie
