发明名称 VECTOR TABLE SELECTION SIGNAL GENERATION CIRCUIT
摘要 PROBLEM TO BE SOLVED: To generate a vector table selection signal through inputs at only one terminal. SOLUTION: An input signal S for selection of a vector table, which signal is inputted to the terminal 11 of an input terminal part 1 during a resetting period, is inputted to a latch circuit 3 via an AND gate 21 included in a terminal function switching circuit 2 and is taken into the latch circuit 3 at the timing of canceling resetting, to hold a non-resetting period. Thus, the outputs of the latch circuit 3 become vector table selection signals during the non-resetting period. COPYRIGHT: (C)2005,JPO&NCIPI
