Error Warning Enable (0 = disabled, 1 =
enabled)
Error Passive Enable (0 = disabled, 1 =
enabled)
0 = No objects whose INT_EN bits are set
currently have a message complete condition. 1
= One or more objects whose INT_EN bits are
set currently have a message complete
condition.
These 5 bits encode the lowest object number
(0 – 31) of all objects whose INT_EN bits are
set AND who currently have a message
complete condition. If there are no such objects
(1orMore = 0), these bits will be 00000b.
001 = Most recent is Rx Buffer Full interrupt.
010 = Most recent is Fragmentation Error
interrupt.
100 = Most recent is Tx Buffer Underflow
interrupt.
These 5 bits encode the object number (0 – 31)
of the Message Object experiencing the most
recent Message Error (Tx Buffer Underflow,
Fragmentation Error, or Rx Buffer Full)
condition. If more than one object are
encountering Message Errors, only the most
recent object number will be available.
