Hello Nordic team,
I'm working on an nrf52840 with the SDK 15.3.0.
I'm using the SPIM instance 3 at 32MHz to interract with a Slave SPI which can support up to 40MHz.
When stressing the SPI access using easyDMA data transfer, I have some SPI errors, so I want to verify the SPI MISO/MOSI timings.
Timings on the nrf52840 datasheet seems to be given for a SPIM frequency of 8MHz.
Especially the value tSPI,VMO = 59ns which is almost 2 periods of 32MHz !
Can you give : tSPI,SUMI & tSPI,HMI & tSPI,VMO & tSPI,HMO values at 32MHz ?
If you have other explanation on this subject i'm looking forward to hearing it !
Thanks in advance,
Regards,
Aloïs KYROU.
