TPS23880: open/close each port by register

Hi,

I need to force open/close each port by register without a valid PD. Below is my register configuration,

1. Reg_0x12=0x55, Reg_0x13=0x00, Reg_0x19=0x0f, force all ports open;

2. 0x14=0xff;

3. Close each port by Reg_0x19;

4. Open each port by Reg_0x14. This is the problem, I can't open the port by this step. Do I need to do other register configurations? 

One more question, I would like to make each port as 70W. Is it Reg_0x29=0xee？

Thanks.
