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
