Jetson Xavier SPI Timing Characteristics

Hi,

For a project, I need to be aware of the SPI setup and hold times. After having digged into the documentation, I open a thread to ask informations about the SPI timing characteristics on the physical level, concerning the SPI bus of the jetson expansion header.

I am looking for the setup and hold times of the MOSI regarding to SCK, of MISO regarding to SCK and of CS regarding to SCK. I’ve seen that CS setup and hold times are tuneable in the TRM but did not find any more information.

Can you provide me these informations?

Best Regards

In CS TIMING_1 register we configure the setup and hold time.

CS_SETUP_TIME: specifies the setup time of the chip select to the data being transmitted or received on CS(0,1, 2 or 3) in terms of number of clock cycles(16cycles Max).

CS_HOLD_TIME: Specifies the hold time of the chip select to the data being transmitted or received on CS(0,1,2 or 3) in terms of number of clock cycles (16cycles Max).

There is no provision to configure the setup and hold times w.r.t MOSI or MISO regarding to clock.

Can you provide much detail information for your issue?
