DP83822 LED_1 pin description in the datasheet

Other Parts Discussed in Thread: DP83822I

Hi,

I have a question about DP83822I bootstrap pin.

In DP83822I datasheet page.47 "Table 13. LED_1 Configuration",
in this talbe there are a line of "Strap Mode".
But from page.46 "Table 10. 4-Level Strap Pins", I can not see LED_1 pin in this table.

Does LED_1 pin  behave as strap pin?

Or is it a typo of datasheet?

best regards,
g.f.

    Hi g.f.,

    LED_1 is not a strap pin. The strap on CRS pin is used to control the configuration of LED_0 and LED_1. Table 13 describes how LED_1 will change with LED_SPEED bit and LED_SPEED bit can be controlled by CRS strap. For e.g. if CRS pin is strapped to mode 1 or 4, then LED SPEED bit will be 0 which will in turn program LED_1 to be in tri state.
