CHAPTER 2 DEPENDENCE FUNCTIONS

2.2.1.1 MCU Operation Mode

There are two MCU operation modes as follows:

• Debugging Mode

• Native Mode

■ Setting MCU Operation Mode

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.

Table 2.2-1 Restrictions on Debug Functions in Native Mode

Applicable series 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.
