METHOD FOR PROCESSING AN INTERRUPT OF A MICRO FIRMWARE LOADER ON A I2 BUS |
摘要 |
PURPOSE: An interrupt processing method is provided, which removes a problem relative to an interrupt which can occur during a download using only a firmware which controls components in common use without a private circuit of a firmware down and can overcome an interrupt problem of a firmware loader of a micro controller firmware loader on a high-speed serial bus. CONSTITUTION: An interrupt processing method comprises the steps of: performing a timer interrupt processing for performing a firmware download in an environment with a limited ROM and RAM, wherein the RAM region for an I2C bus control module resides in an initial part of RAM and then an initial RAM region and a circuit control RAM region are reside in the initial part of RAM; performing an I2C bus interrupt processing; and performing an interrupt processing relative to a serial interface.
