OK,
Now tell me how do you get the trace? Do you turn it on or it shows up sporadically?

HI 2-3us delay means 500-330KHz frequency.
The lower SUB-20 SPI clock frequency is 125KHz isn't it good?

What part is it?

Hi,
Currently not but in next few weeks or month we are going to release new SW/FW version with two additional SPI channels where you could configure lower SPI frequencies.
Anyway I wander why do you need it?

"E201" has 16 bits (i.e 16 GPIO) and you mention only 8.
Anyway you should use
sub_gpio_config : http://www.xdimax.com/sub20/doc/HTML/su ... config.htm
and
sub_gpio_write: http://www.xdimax.com/sub20/doc/HTML/sub_gpio_write.htm

What parameters do you provide to sub_fifo_read and what is the failure code?

And while SUB-20 is processing request from host

It is on while SUB-20 is in bootloader mode
