within the DEU is write-only, so the value displayed in the GUI panel is
always the initial value.
Data Address Breakpoint
A single data address breakpoint enables you to stop the core clock
when the data address is issued to load data from memory or store data
to memory. The data address breakpoint comprises an address value,
enable, mask, counter, and false mode directive. The 24-bit address
value is compared against the load address and the store address for
both the load/store parts of the core. The counter for the data address
breakpoint behaves the same way as the instruction address breakpoint
counter. The 24-bit mask register causes the comparison logic within the
DEU to ignore certain bits in the address. When a bit is set in the data
address mask register, the corresponding bit in the data address
comparison is ignored. The false mode is used to stop the core clock
when the condition indicated by the address and mask fields are false.
Data Value Breakpoint
A single data value breakpoint enables you to stop the core clock when
a specified data value is loaded from memory or stored to memory.
When loads or stores that have a size greater than 16 bits are issued,
the 16-bit data value is compared against every valid 16-bit portion of the
load / store value. The data value breakpoint comprises a data value,
enable, mask, counter, and false mode directive that behave in the same
manner as the corresponding elements of the Data Address Breakpoint.
External Breakpoints
Four external pins are provided that can cause breakpoints. These
controls allow enabling each of the breakpoints based on the input at
these pins.
Combination Breakpoint
The logical combination breakpoint is a logical AND or OR of other
breakpoints. The logical combinations are
