DP83826I: Default Settings for Datasheet Changes.

Kengo.Y

Part Number: DP83826I

Hi team,

Could you tell me about the default settings for datasheet change (~RevF).

1. About the LED1.

I think LED1pin is Active-L.
* I understand Active-L means Low output when it moves.
What is the default setting for LED1?
Also, has the datasheet been changed to change the default setting?

2.About the pin16.
Strap 0 defaults to 0 (Low), but since it is changed to internal PU, doesn't it default to 1 (High)?

Sincerely.
Kengo.

Hi Kengo,

The LED1 polarity is as mentioned in the datasheet, using Reg 469h you can change it. Default setting for LED1 is 5h as mentioned.

Strap0 is default PD, it is a typo.

Rahul,

Thank you for your reply.

I think LED1pin is internal PU.
Therefore, the LED should be active low.
I have the LED connected to GND, but it should not be LED ON, because it is active low.
The operation does not match.

Sincerely.
Kengo.

Hi Kengo,

LED1 is an internal PU as you mentioned.

LED polarity is auto-detected (Active Low/ Active High) based on external pull-up or pull-down on the pin.

Hi Rahul,

Thank you for your comments.

What is the polarity if there is no external PD/PU?

And then, you said the default value of strap0 is a typo.
So, what does this statement explain?

Sincerely.
Kengo.
