This interface establishes communication with the host machine by using the DRST, DCK, DMS, DDI, and
DDO signals, via an on-chip debug emulator. The communication specifications of on-chip debug are used for
this interface. It does not support a boundary scan function.
On-chip debugging can be performed by providing wiring and connectors for debugging on the target system.
Connect an on-chip debug emulator to the emulator connector.
The
The CPU can be started in the debug mode immediately after resetting the CPU has been cleared.
Execution of the user program can be forcibly stopped (however, the handler of the illegal instruction code
exception (first address: 00000060H) cannot be used).
Two common instruction fetch/access breakpoints can be used. By using the instruction breakpoint, program
execution can be suspended at an arbitrary address. By using the access breakpoint, program execution can
be suspended by data-accessing an arbitrary address. In addition to these two breakpoints, a software break
function is available. Up to four software breakpoints can be set in the internal ROM area. The number of
software breakpoints that can be set in the internal RAM area differs depending on the debugger used.
