• The switch state in Block Diagram is for initial resetting.

• Switch turns to ° side for 1 and to • side for 0 in Serial Data Truth Table.

• DFCT switch turns to ° side when defect signal generates for DEFECT = E in Serial Data Truth Table.

• TG1 switch turns to ° side and TG2 switch is left open when TG1 and TG2 (address 1 : D3) is 1.
