Abstract
PURPOSE: To enable to reduce the burden over the software, by determining the sampling period of the data succeeding to the control bit group, based on the logical value stored in the buffer register, count value and data prepared in advance.
CONSTITUTION: The time for every time of specified every logical period of the control bit group at the head of the data transferred from the device 301 is counted by the counter 107, and the count of every given logical period and the logical value of every count period of the counter 107 are tentatively stored in the buffer register 108. Further, based on the logical value stored in the buffer register 108 and the data, of which the count value is prepared in advance, the sampling period of the data succeeding to the control bit group is determined by the device controller 302 by the control logic. Thus, the burden to the software can be reduced.
