Drive Strength Selection (GPO), Too Low Resistance MPC5744P (MBD)

I am using MPC5744P Development and using model based development toolbox for creating the program.

For the GPO write block, I observe that the maximum drive resitsnce is 240 ohm. Which means 3300 mV/ 240 = 137 mA. 

The suggested in the Data Sheet for MPC5444P (DC Injection is 3 mA), for this we need to select 1.1 kilo-ohm.

Could you please help me understand, what is the logic of drive strength  in Simulink blocks. 

Best Regards
