Abstract
When a framing error occurs in a slave unit, the cause of error is analyzed, and an interruption is inhibited or enabled depending on the cause of error thus, optimal data communication can be performed. When an interrupt request is issued, whether or not the interruption is caused by a framing error is determined. If the interruption is affirmatively caused by a framing error, whether or not framing errors occur two or more times is determined. An interruption is not inhibited (i.e., enabled) for a negative determination.
