2.2 Trace Functions

The branch source addresses, mnemonics, operands, and source lines are displayed. Real-time trace acquisition is

supported by the trace buffer incorporated in the device.

Note: The MCUs which have no trace function cannot use this function.

2.3 Break Functions

The E8a emulator has the following four break functions.

(1) Hardware break function

Uses a break controller incorporated in the device.

The access address, instruction fetch address, data, or bus cycle condition can be set.

This function can also be set from the

[Event] column in the [Source] window. For the setting, refer to section 5.3.1

Address Interrupt Breakpoints.

Note: The MCUs which have no hardware break function cannot use this function.

(2) PC break function (BREAKPOINT)

Breaks when the dedicated instruction at the specified address that has been replaced is executed.

This function can be set on the [Breakpoint] page in the [Eventpoint] dialog box. It can also be set when the [S/W

Breakpoints] column for the line to be set is double-clicked in the [Source] or [Disassembly] window.

(3) Forced break function

Forcibly breaks the user program.

(4) Address match break function

Stops the target program immediately before a specified address instruction is executed. This function is featured by

the address match interrupt of the MCU. This function can be set from the

[Event] column in the Source window. For

the setting, refer to section 5.2.2, Viewing the Source Code.

Note: The address match break points vary depending on the device. And, user program operation when device's address

match interrupts are used is not guaranteed.

2.4 Memory Access Functions

The emulator has the following memory access functions.

(1) Memory read/write function

[Memory] window: The memory contents are displayed in the window. Only the amount specified when the

[Memory] window is opened can be read. If the memory is written in the [Memory] window, a

read in the range displayed in the [Memory] window will occur for updating the window. When

the [Memory] window is not to be updated, change the setting in [Lock Refresh] from the popup

menu.

me command: A command line function that reads or writes the specified amount of memory at the specified

address.
