I've a quick question.
I'm enrolled in a project that use the Blackfin BF527 rev. 02 to read some ports via interrupts. I'd like to know what's the time for Blackfin identify a signal on General-purpose ports.
I've noted a long time (~80ns) for Blackfin identify via interrupt a external signal. Please, see the attached.
1) SCLK = 120MHZ;
2) CLK = 600MHz;
3) Interrupt to detect external signals in Port H is mapped on IVG7 (high priority).
Thanks for your attention.
