P1020/P1011 SPI Specific FAQs

[#1]

If SPI is not being used, how should SPI_CLK and SPI_MOSI be terminated in P1020/P1011?

SPI_CLK and SPI_MOSI should be pulled up, if not used.

According to P1020 Design Checklist (AN4259), SPI_CLK should be pulled down with 1K to GND if not used. Can anyone confirm which is the correct way?

See comment from AP application team:

Both are correct and expecting both of them works fine. The general idea of terminating unused signal is to set it to inactive state.
