in my own board. I start a spi master.
and capture the signal of the CSN and SCK.
they looks abnormal
in one burst (package), the CSN has two pulse. I think the CSN only have one pulse for one burst. how the two pulse occurs?
the first pulse at the beginning have 1us width. and the second pulse at the ending have 80 us width.
for the SCK, I find the width of pulse looks not constant.
the two signal is ok?
thanks.
