S1C33 FAMILY DEBUG MONITOR EPSON

OPERATION MANUAL 1

1 S5U1C330M2S Package

The Debug Monitor S5U1C330M2S is a middleware designed for S1C33 Family single-chip

microcomputers.

It provides program-debugging functions on the user target board or for the actual product.

1.1 Features

The following lists the features of S5U1C330M2S:

• It is provided as a library file that can be linked to the user program.

This package also contains source codes of all the modules.

• S5U1C330M2S uses approx. 10KB ROM, approx. 2.5KB RAM and a channel of serial interface on the S1C33

chip. It allows direct program debugging via the S5U1C330MxD1 board using the debugger db33onthepersonal

computer.

• Allows debugging of the target program in the RAM, ROM or Flash memory on the target board.

• Supports the following debugging functions:

- Successive execution and step execution of the program

- PC break and data break

- Memory/register operation

- Flash memory writing

A configuration of the debugging system is shown in Figure 1.1.1.

1.2 Components of S5U1C330M2S Package

The following lists the contents of S5U1C330M2S Package:

When unpacking, make sure that all of the following components are included.

(1) Tool disk (3.5' FD for PC/AT, 1.44MB) 1

(2) S1C33 Family Debug Monitor Operation Manual (this manual) 2 (1 English/1 Japanese)

(3) Warranty 2 (1 English/1 Japanese)

1.3 Installation

S5U1C330M2S needs to be linked with the user program as it is implemented. Therefore, make sure all tools of the

"S1C33 Family C Compiler Package" have been installed in the personal computer and are ready to run before

installing the S5U1C330M2S files. The basic system configuration is described below.

• Personal computer:

IBM PC/AT or compatible

(PC with Pentium 90 MHz or higher and 32MB or more memory recommended)

One channel of the serial port is used to communicate with the debug monitor.

• OS:

Windows95, Windows NT 4.0 or higher version (English version or Japanese version)

All the S5U1C330M2S files are supplied on one floppy disk. Execute the self-extract file "mon33vXX.exe" on the

FD to install the files. ("XX" in the file name represents the version number, for example, "mon33v10.exe" is the

file name of S5U1C330M2S ver. 1.0.)

When "mon33vXX.exe" is started up by double-clicking the file icon, the following dialog box appears.

Enter a path/folder name in the text box then click

[Unzip]. The specified folder will be created and all the

files will be copied to the folder.

When the specified folder already exists on the specified

path, the folder will be overwritten without prompting if

[Overwrite Files Without Prompting] is checked.

The following lists the configuration of directories and files after copying.

... These libraries cannot be used with the ICE or ICD.

Normally, either "mon33ch0.lib" or "mon33ch1.lib" is used according to

the serial I/F channel used. Use "mon33.lib" when providing a serial I/O

circuit separately and when not using the S5U1C330MxD1 board.

2 IMPLEMENTING THE DEBUG MONITOR

EPSON S1C33 FAMILY DEBUG MONITOR

OPERATION MANUAL

2 Implementing the Debug Monitor

This chapter describes how to implement the debug monitor and how to start it from the application

program.

2.1 Resources Required for the Debug Monitor

The debug monitor uses the following resources:

• Approximately 10KB of ROM area for the program code of the debug monitor.

• Approximately 2.5KB of RAM area for the work and stack area.

• Since the debug monitor uses the debugging exception of the CPU, addresses 0x0 to 0xF ofthebuilt-in RAMarea

are used as the vector and stack for processing debugging exceptions. Furthermore, addresses 0x10 to 0x2F are

reserved for extending functions.

• One channel (Ch.0 or Ch.1) of the serial interface (8-bit asynchronous mode) is used for communicating with the

debugger db33 on the personal computer.

Figure 2.1.1 shows a connection diagram.

Figure 2.1.1 RS232C connector diagram

• Communication via RS232C is performed by a software polling method without any interrupt related resource.

• A serial I/O device outside the S1C33 chip can be used by customizing the serial I/O routine (see Section 2.4).

• S5U1C330M2S uses the TXD, RXD and status registers of thecorrespondingserial interfacechannelexclusively.

Therefore, do not access these control registers.

Furthermore, fix the I/O pins for the channel at the serial interface pins using the port function select register. For

example, the sample program "m3s_sci.s" writes 0x07 to the P0 function select register (0x402D0) when Ch.0 is

used or 0x70 when Ch.1 is used to set the serial interface pins.
