Abstract
The present invention provides a mode setting determination signal generation circuit for generating a mode setting determination signal based on a power-on signal applied during power-up, including signal generation means for generating an output signal fixed either to a high or low level, a first logic circuit section for outputting a signal based on a NOR or OR logic between the output signal from the signal generation means and the power-on signal, a second logic circuit section for outputting a signal based on a NAND or AND logic between a power-on signal having a polarity opposite to that of the power-on signal and the output signal from the signal generation means, a third logic circuit section for outputting a signal based on a NAND or AND logic between a signal at a mode setting determination signal output terminal thereof and the output signal from the second logic circuit section, a transfer gate circuit section for outputting either the output signal from the third logic circuit section or a mode setting signal as an output signal based on a mode setting control signal, and a fourth logic circuit section for outputting a signal based on a NAND or AND logic between the output signal from the transfer gate circuit section and the output signal from the first logic circuit section.
