Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system. In particular, a board in a mobile communication system compares write data with read data during an error correction operation (S5), so that a problem related to memory can be easily recognized quickly, and a memory is not mounted on the board. When mounted to the system in a state that the LED is blinking (S8) has the effect that the user can easily know this.

Description

Method of verifying and testing whether a memory is mounted on a board incorporating a MC683 series}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system, and in particular, various types of memory (DRAM, SRAM) is to check whether it is mounted.

In the board of the conventional mobile communication system, it was not possible to check whether various kinds of memory are mounted, and even during error correction, the user spends a lot of time ignoring whether the memory is mounted, so that the user opens the cassette in which the various memories are built and checks them individually. There was a problem.

An object of the present invention is to solve the above-mentioned conventional problems. In particular, when a memory is not mounted in a board using the MC683 series communication controller, the memory is mounted by flashing a specific light emitting diode on the board. It provides a “how to check and test memory mounting on boards using MC683 series” to show if there are any.

In order to achieve the above object, the present invention "memory mounting test method and test method in the board using MC683 series", the initialization to correctly initialize the dual port RAM (DUAL PORT RAM) in the controller to the desired function Step S1; An EPROM setting step (S2) for setting a global chip select (GPOBAL CHIP SELECT) and a memory bank for using an EPROM or chip selects for a desired use; A memory write step WRITE for writing arbitrary data to the memory; A data read step S4 of reading arbitrary data from the memory; A data comparing step S5 for comparing the write data with the read data; A comparison data checking step (S6) of checking whether the compared data within the range of the memory is the same and performing again from the memory writing step (S3) if not the same; If the compared data is different, the memory is bad or unmounted, so that a routine (ROUTINE) for flashing a specific light emitting diode or a controller stopping step (S7) is executed; The LED blink routine comprises a light emitting diode blink step (S8) that blinks using a particular address ADDRESS and the parallel input / output port of the controller.

The present invention "memory mounting and test method of the board using the MC683 series series" is a board in the mobile communication system compares the write data and the read data during the error correction operation (S5) easily and quickly in case of problems related to memory If the memory is not mounted on the board in the system, the LED is blinking (S8), so that the user can easily recognize this effect.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

EXAMPLE

First, initialize the dual port RAM in the controller according to the desired function (S1), set the global chip select, memory bank, and other chip selects for use of the EPROM (S2), and write arbitrary data to the memory (S3). Read arbitrary data from the memory (S4), compare the write data with the read data (S5), check if the data compared within the range of the memory is the same and if it is the same, perform again from the memory write step (S3), or perform the next step. (S6) If the compared data is different, the memory is bad or unmounted, so perform a routine (ROUTINE) to stop a specific light emitting diode (ROUTINE) or stop the controller (S7). The output port can be used to flash a light emitting diode to inform the user of the memory mounting status. It will be.

As described above, the present invention "memory test method and test method for the board using the MC683 series", in particular, the board in the mobile communication system compares the write data and the read data during the error correction operation (S5) memory and In case of related problems, it is easy to know quickly, and when the memory is not mounted on the board, the LED is blinking (S8), so that the user can easily recognize the effect.

1 is an operational flow chart showing a "method for confirming and testing a memory mounting on a board using MC683 series array" according to an embodiment of the present invention.
