CHAPTER 2  DEPENDENCE FUNCTIONS

■

Set the MCU operation mode.

There are two operation modes: the debugging mode, and the native mode. Choose either one using the SET

RUNMODE command.

At emulator start-up, the MCU is in the debugging mode.

When the MCU operation mode is changed, all the following are initialized:

- Data breakpoints

- Event condition settings

- Sequencer settings

- Trace measurement settings and trace buffer

- Performance measurement settings and measured result

●

Debugging Mode

All the operations of evaluation chips can be analyzed, but their operating speed is slower than that of mass-

produced chips.

●

Native Mode

Evaluation chips have the same timing as mass-produced chips to control the operating speed. Note that the

restrictions the shown in Table 2.2-1 are imposed on the debug functions.

Restrictions on debug functions

MC-16/16H 

- Memory mapping setting is disabled and each area is accessed to the MCU 

specifications.

- Traces cannot  be disassembled. 

Common to all series 

- When a data read access occurs on the MCU internal bus, the internal bus 

access information is not sampled and stored in the trace buffer.

- Even when a data break or event (data access condition) is set for data on the 

MCU internal bus, it may not become a break factor or sequencer-triggering 
factor.

- The coverage function may fail to detect an access to data on the MCU 

internal bus.
