摘要：
A control device for use in a sewing machine and a control method in which the memory contents of a memory element are read when a servo microcomputer generates an interrupt. The control device also changes sewing data by specifying a rewriting format when sewing data are changed, automatically detects the rewriting of the memory contents of a rewritable memory element due to noise, and restores the memory contents to their original state before they have actually been rewritten.
