TDA4VM: How to control GPIO0~7 in main domain.

Hi 

expert.

I'd like to control GPIO1_11(U2 ball) on <-> off.

I set reset value(0x08214007) in PADCONFIG140 (addr: 0x00011C230). I supposed GPIO7 because PADCONFIG140 is 0x00011C230 and 1C230 is partition7.

I set value (0x00000800) in DIROUT01 (addr: 0x00680010)

I set value (0xd172b45a) in OUT_DATA01 (addr: 0x00680014). Default value of OUT_DATA01 is "0xd172bc5a" so I reset bit11 to 0.

but GPIO is out 1. I expected 0.

 

Is this set value right? and I want to know how to select GPIO0~7 bank. What is VGPIO_SEL option?

Thank you.
