8051 ISP-ICP Programmer

User Manual, v5.41

1 Introduction

ISP is the acronym of In-System Programming, and ICP is the acronym of In-Circuit Programming. Both these

two programming methods make it possible that the user can update the application code under the software

control without removing the mounted MCU chip from the actual end product. The tool “Megawin 8051 ISP-ICP

Programmer”, see the following picture, integrates these two functions into a USB stick. That is it can function as

an ISP Programmer and an ICP Programmer. In addition, because the programming data to be programmed to

the target can be saved in the programmer’s non-volatile storage, this programmer is able to work stand-alone

without host (PC) intervention. This feature is especially useful in the field without a PC.

Picture of the ISP-ICP Programmer

1.1 Two-in-One Functions

ISP Programmer

When acting as an ISP Programmer,it functions like a bridge between the host, which provides the new

programming data, and the target MCU, which has the loader program running inside. The loader program is the

so-called “ISP-code” and should be pre-programmed in the ISP-memory of the target. When powered on, the

target boots from the ISP-memory and executes the ISP-code to check if the ISP operation is requested. If the

ISP is requested, the target receives the programming data from the Programmer and programs into the AP-

memory by in-system programming method. After ISP processing is completed, the target will re-boot from the

AP-memory to run the new application code when the Programmer is plugged out of the target; If the ISP is not

requested, the target will directly re-boot from the AP-memory for normal running of the application code.

ICP Programmer

When acting as an ICP Programmer, it actually functions fully like a universal programmer except it adopts a

serial interface with only four pins used for programming. So, there is no need to have a loader program

embedded inside. It provides all the programming functions which a universal programmer can support, such as:

(1) erase the device,

(2) program the device,

(3) verify the device, and

(4) program all the device H/W options, including the security bits.

Note:

1. So far, only the MPC82G516 and MG84FL516 support both ISP and ICP.

2. ISP interface always uses P3.1 as DTA pin while ICP interface uses dedicated SDA and SCL pins.

2 Chip Configuration for ISP

To use the ISP function, the user should configure the target MCU by the following two steps:

Step1:

Use a universal programmer or “Megawin 8051 Writer” to configure ISP-memory with 1K bytes (or 1.5K bytes for

MPC82L(E)54 ) and make HWBS or HWBS2 option enabled.

Step2:

Program the Megawin-provided standard ISP code in the [(3) Target ISP-code] folder into the ISP-memory. Note

"ISP_Code_v6.00.bin" is for MPC89/MPC82/MG87-series MCU, and "ISP_Code_v5.00_MG84.bin" is for

MG84-series MCU.

Note:

To let users easily use the ISP function, the Megawin 8051 products will have the following factory setting:

(1) ISP-memory is configured with 1K (or 1.5K) bytes and “HWBS” option is enabled.

(2) The Megawin-provided standard ISP-code is pre-programmed.

So, the user has no need to do the chip configuration before using the ISP function.

3 Install the ISP-ICP Programmer

3-1 Install the Driver

Plug the ISP-ICP Programmer into the PC’s USB port, and do as follows when the monitor shows a prompt about

new hardware found.

1) Select No, not this time, click Next.

2) Select Install from a list or specific location, click Next.

3) Select Search for the best driver in these locations and Include this location in the search, click Browse.

4) Locate the driver folder [(2) PC-site Driver], click OK.

5) Click Next. The driver installation starts.

6) Click Finish when the installation completes.

To check if the Programmer was correctly installed, follow the listed steps:

1) Open the My Computer folder.

2) Open the Control Panel folder.

3) Open the System.

4) Click on the Hardware tab at the top of the dialog box, then click on the Device Manager.

5) Click on the plus sign in front of the Universal Serial Bus Controllers to check the device listing.

If the installation was completed successfully, you may find an entry, Megawin 8051 ISP-ICP Programmer, in the

listing.

3-2 Install the AP

Run “Setup.exe” (in the [(1) PC-site AP] folder) to install the application program for the ISP-ICP Programmer on

your PC. Using its default installing setting, you will find the item “Megawin Utilities \ Megawin 8051 ISP-ICP

Programmer (v?.??)” appearing in the Windows START-menu.

(Note: the v?.?? means the current version and may be upgraded in the future.)

3-3 Introduction to GUI of the PC-site AP

GUI means “Graphic User Interface” of the Application Program running in the Windows.

The PC-site software AP (Application Program) integrates both functions of the ISP Programmer and the ICP

Programmer. The first thing the user needs to do is to select the “Programmer Type” when the AP is opened. See

the following figures for these two programmer types.

About the H/W Option Setting

The user should always configure proper H/W Option before clicking “Update Target” or “Update Programmer”.

FZWDTCR:

[enabled]: The WDTCR register will be initialized to its reset value (0x00) only by power-on reset.

(For example, if WDTCR=0x2D, it still keeps at 0x2D rather than 0x00 after RST-pin, S/W or WDT

reset.)

[disabled]: The WDTCR register will be initialized to its reset value (0x00) by all reset (including power-on,

RST-pin, S/W and WDT reset).

OSCDN:

[enabled]: If the XTAL frequency is less than 25MHz, this option can be enabled to reduce the internal

oscillating gain for lower EMI.

[disabled]: Normal oscillating gain.

EN6T:

[enabled]: MCU runs at 6T mode (6 clocks per machine-cycle, double speed compared to a traditional 8051)

[disabled]: MCU runs at 12T mode (12 clocks per machine-cycle, like a traditional 8051)
