Inbound Message x Status Registers (IMxSR)
IMxSR reports various mailbox conditions during and after a message operation. Writing a value
of 1 to the corresponding set bit clears the bit.

0
Queue Full
If the queue becomes full, this bit is set.
QF is cleared when the queue is not full and if the message controller is disabled. Read only.

MIQ
16
0
Message-In-Queue
If the queue has accumulated the number of messages specified by the IMxMR[MIQTH], this bit
is set.
MIQ is cleared when the number of message in the queue is less than the number specified by
IMxMR[MIQ_THRESH] and if the message controller is disabled. Read only.

0
Message Request Time-Out
Set when the message unit has not received another message segment for a multi-segment
message and a time-out occurs. This bit is cleared by writing a 1 to it.
For proper operation, this bit should be modified only when the inbound message controller is
not enabled.

0
Reserved. Write to zero for future compatibility.
TE
7
0
Transaction Error
Set when an internal error condition occurs during the message operation. TE is cleared by
writing a 1 to it.
For proper operation, this bit should be modified only when the inbound message controller is
not enabled.
