UPF Update Flag
If set to 1, Interrupt Loglist Entry was updated
AEI Any Error Interrupt
If set to 1, an interrupt was asserted if any error was detected during transfer.
IXI Index Interrupt
If set to 1, an interrupt was asserted due to the current buffer index.
PGI Programmed Transfer (BC) or SA (RT) Interrupt
For BC: If set to 1, an interrupt was asserted due to programmed BC
Iinterrupt.
For RT: If set to 1, an interrupt was asserted due to programmed RTSA
Iinterrupt
BCH Bus Controller Halt
If set to 1, an interrupt was asserted due to BC Halt (1553 protocol only)
UXI Unexpected (Status Word) Response Interrupt
If set to 1, an unexpected Status Word response interrupt was asserted (1553
protocol only)
METI Monitor External Trigger Event during bus idle time
If set to 1, an interrupt was asserted if no bus traffic takes place and an
external trigger event was detected. This trigger type provides neither a
trigger control block index (TCBI) nor a monitor buffer pointer (MBP) to the
interrupt loglist entry (1553 protocol only)
MTI Monitor Trigger Interrupt
If set to 1, an interrupt was asserted if a trigger event becomes valid during
the trigger control block processing (1553 protocol only)
MBF Monitor Buffer Full Interrupt (or Half Buffer Full Interrupt in Recording
Mode)
If set to 1, an interrupt was asserted due to the Monitor Buffer Full event is
standard or selective data capture mode and due to the Half Buffer Full event
in recording mode
MSI Monitor Start Interrupt
If set to 1, an interrupt was asserted due to a Monitor start trigger event
MST Monitor Stop Interrupt
If set to 1, an interrupt was asserted due to a Monitor stop trigger event (1553
protocol only)
