TPS38700: AF Enable settings in GPO9,11,12

Hi Team,

My customer wanted to use EN[12:9] as GPO[12:9]. we cannot write in 0x20. 

Regarding to the datasheet,  "The alternate function can be enabled only if the corresponding PU/ PD/ SLP_EXIT/ SLP_ENTRY registers fields are all set to 0".that means we can set 0x0C in 0x20 by writing the following command?

    0x3B PWR_EN9  = 0x00

    0x3D PWR_EN11 = 0x00

    0x3E PWR_EN12 = 0x00

    0x5B SLP_EN9  = 0x00

    0x5D SLP_EN11 = 0x00

    0x5E SLP_EN12 = 0x00

Thanks,

Shoo
