CC2541: I2C + IAR. How to change SCL/SDA pins?

Part Number: CC2541
Other Parts Discussed in Thread: CC2540, CC2530

Hello!

I tried to use HM-11 PCB with CC2541 onboard as low-cost BLE sensor.

HM-11 has only Tx, Rx, P2.2, P2.1 connected.

I want to use this pins to communicate with I2C sensor.

In SCS & CCS i can manually set SCL, SDA pins for I2C.

How can i do it in IAR?
