Resulting Set of Possible Trigger Combinations
The resulting set of possible breakpoint trigger combinations consist of the following options where ||
denotes logical OR, && denotes logical AND, and {} denotes an optional additional trigger term:
One-level triggers of the form:
if
(PC_breakpoint)
if
(PC_breakpoint|| Address_breakpoint{&& Data_breakpoint})
if
(PC_breakpoint|| Address_breakpoint{&& Data_breakpoint}
||
Address1_breakpoint{&& Data1_breakpoint})
if
(Address_breakpoint
{&& Data_breakpoint})
if
((Address_breakpoint
{&& Data_breakpoint})
||
(Address1_breakpoint{&& Data1_breakpoint}))
if
(Address1_breakpoint
{&& Data1_breakpoint})
Two-level triggers of the form:
if
(PC_breakpoint)
then if
(Address_breakpoint{&& Data_breakpoint})
if
(PC_breakpoint)
then if
(Address_breakpoint{&& Data_breakpoint}
||
Address1_breakpoint{&& Data1_breakpoint})
if
(PC_breakpoint)
then if
(Address1_breakpoint{&& Data1_breakpoint})
if
(Address_breakpoint
{&& Data_breakpoint})
then if
(Address1_breakpoint{&& Data1_breakpoint})
if
(Address1_breakpoint
{&& Data1_breakpoint})
then if
(Address_breakpoint{&& Data_breakpoint})
if
(Address_breakpoint
{&& Data_breakpoint})
then if
(PC_breakpoint)
if
(Address1_breakpoint
{&& Data1_breakpoint})
then if
(PC_breakpoint)
if
(Address_breakpoint
{&& Data_breakpoint})

EAR1
Address enable bit: Enable address breakpoint range. The breakpoint is based on the inclusive
range defined by ABLR1 and ABHR1. Trigger if address Š ABHR or if address ð ABLR.
2
EAL1
Address enable bit: Enable address breakpoint low. The breakpoint is based on the address in the
ABLR1. Trigger address = ABLR
