An operation monitor system externally outputs a sufficient amount of condition information that indicates an internal operation condition, without using a dedicated terminal, that is to say, without a significant increase in cost. An output control unit of a semiconductor apparatus specifies an IF unit that is not currently performing input/output with respect to an IO unit, selects a selector connected to the specified IF unit, and outputs thereto a select signal indicating that the selected selector is to be used in the output of an internal operation output signal (internal monitoring data), which is the operation condition. The selector that has received the select signal selects the internal condition output signal, and outputs the selected internal condition output signal to an information collection apparatus via the IO unit. The information collection apparatus receives data from the semiconductor apparatus via connection terminals of the semiconductor apparatus, and select the internal monitoring data from among the received data.
