JTAG Test Access Port and OnCE
22.14.11 Enabling OnCE Memory Breakpoints
22.14.12 Pipeline Information and Write-Back Bus Register
Advance Information
602
When the OnCE memory breakpoint mechanism is enabled with a
breakpoint counter value of zero, the device enters debug mode after
completing the execution of the instruction that caused the memory
breakpoint to occur. In case of breakpoints on instruction fetches, the
breakpoint is acknowledged immediately after the execution of the
fetched instruction. In case of breakpoints on data memory addresses,
the breakpoint is acknowledged after the completion of the memory
access instruction.
A number of on-chip registers store the CPU pipeline status and are
configured in the CPU Scan Chain Register (CPUSCR) for access by the
OnCE controller. The CPUSCR is used to restore the pipeline and
resume normal device activity upon return from debug mode. The
CPUSCR also provides a mechanism for the emulator software to
access processor and memory contents.
