Abstract
A data communication device includes: a fixed value memory that stores a fixed value; a received data memory that stores received data inputted through a bus; an output data memory that stores output data; a comparison determination unit that outputs a comparison determination result signal indicating a determination result of comparing the fixed value and a value of the received data; a data output unit that has a first state of outputting the output data to the bus and a second state of not outputting the output data to the bus; a command analyzing unit that outputs a data output control signal based on a command; and an output controller that outputs a control signal for controlling the data output unit to enter the first state or the second state based on the comparison determination result signal and the data output control signal.
