TPS65987D: Config App for Register 0x27 Global System Configuration

Ilya Tsunaev

Part Number: TPS65987D

Hi,

I'm seeing that the tool allow you to configure "Power Duo Mode". What is this bit [52]?

Bit [52], according to the spec I have, is reserved.

It seems like the bit was meant to configure Byte 8 bits [3:0] to dedicate PP to certain VBUS, which is exactly what I'm looking to do.

Could you please confirm if it's a documentation or configuration application issue or perhaps my misunderstanding?

How can I change PP_SW_MAP during boot (not run time register change)?

Thanks,

Ilya

Hello,

Power Duo mode allows for both internal power paths to be enabled at the same time so that you can use both power paths as either a source or sink.

You can read about it more from the following reference design users guide

Thanks,

Can you clarify the discrepancies between documentation and configuration tool (v6.1.1)?

This is a discrepancy with the host interface technical reference manual

You cannot change these registers during run time. This can only be controlled using the application configuration tool
