5.11 Tutorial Program

5.11.1 Notes on Operating the Tutorial Program

To operate the High-performance Embedded Workshop according to the description of section 4, Tutorial, the

following procedures must be added or modified.

Table 5.11 Notes on Operating the Tutorial Program

4.6 Executing the

Program

Reset the target MCU before executing the program. Refer to section 4.14,

Resetting the Target MCU for how to reset the target MCU.

4.12.3 Executing the

[Step Over] Command

In this product, after execution of [Step Out], execution stops at the statement where

the sort function is called. Before executing the [Step Over] command, execute the

[Step In] command once so that the execution stops at the statement where the

change function is called.

5.12 Memory Map

5.12.1 Emulation Memory

1. The emulator manages areas in the memory blocks shown in figures 5.1 and 5.2. Emulation memory and

user memory cannot coexist in a single block.

2. When emulation memory is used in 50-MHz operation, one or more cycles are required as wait-state cycles

for access to those areas to which emulation memory is allocated. When emulation memory is used, refer to

the table below and set the number of wait cycles for the bus-state controller.

External Operating Frequency Number of Required Wait Cycles

50 MHz One or more

40 MHz or lower 0

5.12.2 Controlling Memory Map

The memory map is divided into the 128-kbyte, 1-Mbyte, or 2-Mbyte blocks in each CS area. The accessing

attribute can be changed in a unit of each block. For the size of blocks used for each CS area, refer to figure 5.1

or 5.2.

This emulator incorporates the 4-Mbyte emulation memory, which can be divided into 128 kbytes (x 16) and 1

Mbyte (x 2).

The emulation memory can also be set in a unit of each block (figure 5.1 or 5.2), as well as in the accessing

attribute. Some 128-kbyte emulation memory is set for the 1-Mbyte or 2-Mbyte blocks. However, the remaining

area of the allocated block cannot be used. This also applies to a case when one 1-Mbyte emulation memory is

allocated to the 2-Mbyte blocks.
