Part Number: AWR2243

Hi, experts

Why are the descriptions of SPI mode used by awr2243 different in these two documents?

Which SPI mode is used by awr2243?

The picture on the left is from file MMWAVE DFP User Guide.

The picture on the right is from file mmWave Radar Interface Control Document.

Hello Tao,

This looks like a misprint/Typo in one of the documents.

Please give me some time to analyze this and I shall get back to you tomorrow with my insights.

Hi Tao,

The correct Mode is Clock Mode 0 (polarity =0, phase =0)

By clock mode 0 here, we mean - Data is output on the rising edge of SPICLK and input data is latched on the falling edge.
