SN65DSI83: I2C only enabled when in ULPS state

Martin Meijerman

Part Number: SN65DSI83

Dear Reader,

The datasheet of this device states the following:

"The SN65DSI83 device local I2C interface is enabled when EN is input high, access to the CSR registers is
supported during ULPS."

Does this mean ONLY in this state or including this state?

Thanks in advance!

Best regards,

I just realized that my question is as am ambiguous as the datasheet... I meant the ULPS, not the "EN is input high"

Hello Martin,

The register access is enabled in both states when EN is input high and during ULPS.

Hi Joel,

Thanks for the good news, this makes initialization of the device a lot easier than I initially expected.

Best regards,

Martin
