Critical Issue
When the CPRI IP core detects excessive line code violations
(LCVs), it should set the los_lcv field of the CPRI_STATUS register
and assert the cpu_irq_cpri output signal (bit [4]
of the cpu_irq_vector output signal). However, the
issue is that the register field might not be set and cpu_irq_cpri might
not assert even in the case of excessive LCVs.
This issue has no workaround. Do not rely on the cpu_irq_cpri output
signal to indicate LCV errors.
This issue is fixed in version 12.1 of the CPRI MegaCore function.
