METHOD FOR AVOIDING UNWANTED RESET IN TWO IC HAVING DIFFERENT POWER ON RESET VOLTAGE RANGE

摘要

The present invention relates to a method for processing a reset of a MICOM and, more particularly, to a method for processing a reset signal of a MICOM to avoid an unnecessary reset between two integrated circuits (IC), such as a power regulator and a MICOM, having different power on reset voltage ranges. The objective of the present invention is to provide a method for processing a reset of a MICOM, which can solve a problem that a MICOM is unnecessarily reset even when there is a difference in power on reset voltage between a power regulator and the MICOM. To achieve the objective of the present invention, the method for processing a reset of a MICOM comprises the steps of: determining whether a power on reset of a power regulator is performed; generating a power regulator reset signal when the power on reset of the power regulator is performed; transmitting the generated power regulator reset signal to a MICOM; entering an interrupt service routine according to the transmitted power regulator reset signal; detecting a power supply-side voltage monitored by a voltage measurement unit; determining whether the detected voltage is within the range of a MICOM power on reset voltage; and generating a MICOM reset signal when the detected voltage is within the range of the MICOM power on reset voltage.
