A single, high level error condition can generate numerous false interrupts. For
example, an LOF error can generate almost all ATM related errors, HEC errors,
LOCD, etc. To simplify software interrupt routines, the CX28250 automatically
suppresses lower level interrupts when the errors shown in
LOF
