iMX6UL - DDR ADDR drive strength read-only

For the iMX6UL, why is the drive strength (DSE) setting for DDR ADDRn pins in IOMUX read-only?

 

For example, see the IOMUXC_SW_PAD_CTL_PAD_DRAM_ADDR00 section of the reference manual:

 

 

I would have expected the DSE bitfield to have a variety of configurable options, since ADDR is an output of the iMX6...  But instead DSE is disabled and read-only.
