Apparatus and method for outputting result of monitoring

An apparatus includes a functional circuit that operates based on power provided by a first positive supply voltage and a first negative supply voltage; a monitoring circuit operating based on power supplied by the second positive supply voltage and the second negative supply voltage, and generating a first monitoring signal based on monitoring of operation of the functional circuit; and an output circuit that generates a second monitoring signal based on monitoring of the first positive power supply voltage, generates a third monitoring signal based on monitoring of the second positive power supply voltage, and generates an output signal output through the one or more output pins based on the first monitoring signal, the second monitoring signal, and the third monitoring signal. 一种设备包括：功能电路，其基于由第一正供电电压和第一负供电电压提供的电力来操作；监视电路，其基于由第二正供电电压和第二负供电电压提供的电力来操作，并且基于对功能电路的操作的监视来产生第一监视信号；以及输出电路，其基于对第一正供电电压的监视来产生第二监视信号，基于监视第二正供电电压产生第三监视信号，以及基于第一监视信号、第二监视信号和第三监视信号产生通过一个或多个输出引脚输出的输出信号。
