Description

Register Modification Method of Integrated Circuit {REGISTER CORRECTING METHOD FOR IC}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for modifying a register of an integrated circuit, and more particularly, to a method for modifying a register of an integrated circuit that enables modification of a register value described in each integrated circuit in a system without software or hardware replacement.

Typically, embedded systems contain a number of standardized integrated circuits and processors or microcomputers for control.

In order to change the REGISTER value of the integrated circuit IC after the product release, the processor or the microcomputer must be changed or the software used can be modified.

Since the software is not easy to modify, it is possible to correct an error not found at the time of development by modifying the register value by replacing the hardware.

As such, in order to modify the registers used to control each integrated circuit using a processor or a microcomputer in the conventional embedded system, the processor or the microcomputer needs to be replaced. there was.

In view of the above problems, an object of the present invention is to provide a register modification method of an integrated circuit capable of changing a resist of an integrated circuit without updating software or replacing hardware.

1 is a flowchart of a register modification method of an integrated circuit of the present invention.

Figure 2 is an embodiment of a register edit menu window used in the present invention.

FIG. 3 is an embodiment of a register edit menu window in a state in which data is modified in FIG.

FIG. 4 is an embodiment of a register editing menu window for editing a register of another sub-address in FIG.

The above object is achieved by invoking the state of the YPIROM in which the registers of the respective integrated circuits are stored according to a user's operation and implementing an interface capable of editing the same. The present invention will be described in detail with reference to the accompanying drawings. The explanation is as follows.

1 is a flowchart of a method for modifying a register of an integrated circuit of the present invention, in which a user manipulates a key to display a register modification menu window on a display of an embedded system; Changing a register of a specific integrated circuit in the register modification menu window; The modified register is stored in an EEPROM.

Hereinafter, the present invention as described above will be described in more detail.

First, the embedded system displays a register modification window for displaying a state of a register according to a user's key input.

The registers of the respective integrated circuits are stored in an Y pyrom provided in an embedded system, and the registers displayed in the register modification window may sequentially display the registers stored in the Y pyrom.

As shown in Fig. 2, the register modification window displays an item ITM and a value VALUE of the item, and the displayed value can be selected by the user through a key operation to change the value.

The item ITM consists of an IC name representing a unique number for recognizing each integrated circuit, a sub address, an address name, and data.

In the IC name, a unique number indicating each integrated circuit is displayed.

In FIG. 2, the subaddress, the address name, and its data of the integrated circuit whose IC name is IC_1 are shown.

The sub address represents the address of the selected integrated circuit, and the address name represents the name of an item divided into bit fields in the sub address.

That is, the data in one sub-address may be divided into bit units and controlled for each bit unit.

The data item represents data recorded in an item divided into bit fields among sub-addresses.

In other words, the sub-addresses of the same integrated circuit are divided by bits to display the data described in the bits.

Then, the user can select an item by using the cursor up / down keys, and in the selected item (ITEM), the user can modify the value (VALUE) of the item (ITEM) by using the left / right keys.

Then, after modifying the value of the item ITM as described above and storing it, the modified register value is stored in EEPROM.

FIG. 3 is an exemplary diagram in which the data value is modified in FIG. 2. As shown in FIG. 2, an integrated circuit whose IC name is IC_1 has a sub address of 0x1 and bits of the sub address. The data of the area where the name of the bit field is Name_1 was 0x23 initially, and the value of the data item was modified to 0x24 by the user's operation, and this modified value is stored in YPIROM.

The modified registers stored in this pyrom do not operate according to the modified registers immediately and are applied when the embedded system is rebooted.

FIG. 4 is an exemplary diagram when another sub address and address name of the sub address is called in order to change the value of another data item of the integrated circuit whose IC name is IC_1. As shown therein, another sub-address (0x2) of the IC_1 is called, and data 0x7 of the area whose address name is Mame_2 is displayed, which can be modified.

In this way, the register can be changed for each integrated circuit, and the data value of the previous state is stored in case the wrong value of the register is changed, and it is modified by using the RESTORE button in the register modification menu window. The register value can be restored to its previous state.

That is, even if a wrong register is inputted by a user mistake, the previous state can be recovered, and the register restored to the previous state can be modified again, or the state can be stored in YPIROM.

As described above, the present invention makes it easy to modify a register of each integrated circuit stored in an EPROM without replacing software or hardware for editing a register, thereby facilitating the operation of modifying the register. There is a saving effect.
