An information processing device includes a first functional section having an external terminal, and a second functional section and a third functional section, which are commonly coupled to the external terminal of the first functional section. The first functional section includes a first internal circuit that is associated with the second functional section, a second internal circuit that is associated with the third functional section, a switch that can select the first internal circuit or the second internal circuit, and a switch control circuit that controls the operation of the switch. While the second functional section is enabled, the switch control circuit controls the switch so that the first internal circuit is coupled to the second functional section. While the third functional section is enabled, the switch control circuit controls the switch so that the second internal circuit is coupled to the third functional section. |
