I have questions regarding a couple interrupts that are being observed at run-time in this post.
False Carrier Sense interrupt (MISR1, bit 9)
- What are the causes?
- Can you confirm that reading MISR1 and reading FCSCR is the correct way to clear the interrupt?
MDI Crossover Change interrupt (MISR2, bit 11)
- What are the causes?
- How do I clear it?
