Abstract

PURPOSE:To automatically perform the logging processing and to efficiently perform data analysis based on the dump processing, by storing extracted logging data in a shift register and setting the timer value of a timer to the leading part of logging data. CONSTITUTION:Shift registers 1 and 2 in which logging data obtained by logging reception data and/or transmission data to be transferred is stored and a timer 3 are provided; and at the time of DMA transfer of reception data and/or transmission data, extracted logging data is stored in shift registers 1 and 2 and the timer value of the timer 3 is set to the leading part of logging data. Thus, the logging processing can be performed simultaneously with data transfer at the time of data transfer based on DMA control, and data analysis at the time of dumping is effectively performed because the timer value is set to the leading part of logging data.
