Analyzing the PowerPC 604
Trigger Menu
To change the trigger conditions
You can use the trigger menu to change the triggering and storage
qualification to include or exclude specified cycles.
Excluding tenure from other bus masters
In a system in which devices other than the PowerPC 604 assume bus
mastership, you can exclude tenures by other masters by defining new terms
and changing store qualification. Define the terms MYDAT and MYADD,
where:
MYDAT
=
(oDat = l)• (TA= 0)
MYADD
=
(oAdd = l)• (AACK = 0)
Change the store qualification to the ORed combination MYDAT + MYADD,
as shown in the following figure.
