A.18 TBU interrupt signals

The TBU interrupt signals are edge-triggered. The interrupt controller must detect the rising edge of these signals.

The MMU-600 TBU cannot output these interrupts as Message Signaled Interrupts (MSIs). These signals must be connected to an interrupt controller.

The following table shows the TBU interrupt signals.
