Registers

14.7.2.14 EVENT: Local LAI Event Register

This register sets a bit if a local event is hit. Except for QUALFLAG, most local event

signal internal to the AMB may assert for only one cycle. The event bits in this register

remain set once asserted so that the history of the event being set is not lost.

Note: The 5-bit select fields in the EVENTSEL0, EVENTSEL1, EVENTSEL2 and EVBUS

registers use the bit mapping of this register to identify which local event to select.

• For example, if EVENTSEL1.laitrigger0[4:0] = 26 decimal then trigger0 is

connected to the SB CRC error event.

• For example, if EVENTSEL1.laitrigger0[4:0] = 12 decimal then trigger0 is

connected to the inbound EVBus[0] event, and so forth.
