18.3.11 Resulting Set of Possible Trigger Combinations

The resulting set of possible breakpoint trigger combinations consists 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	(Address_breakpoint {&& Data_breakpoint})

Two-level triggers of the form:

if	(PC_breakpoint)
	then	if	(Address_breakpoint{&& Data_breakpoint})
if	(Address_breakpoint {&& Data_breakpoint})
	then	if	(PC_breakpoint)

In these examples, PC_breakpoint is the logical summation of the PBR0/PBMR, PBR1, PBR2, and PBR3 breakpoint registers; Address_breakpoint is a function of ABHR, ABLR, and AATR; Data_breakpoint is a function of DBR and DBMR. In all cases, the data breakpoints can be included with an address breakpoint to further qualify a trigger event as an option.

The breakpoint registers can also be used to define the start and stop recording conditions for the PST trace buffer. For information on this functionality, see Section 18.3.3, “Configuration/Status Register 2 (CSR2)”.
