ABSTRACT:
A scan control apparatus performs data scan-in operation to data storage elements each constituting a bit of data unit. Data of the plural data storage elements designated by scan address are read out into a register where the data at the bit position designated by the scan address is replaced by data to be scanned-in. Subsequently, the plurality of the data storage elements are reset simultaneously to thereby set the data in the register to the original data storage elements.
