DATA PROCESSING DEVICE AND DATA PROCESSING SYSTEM

摘要

A data processing device is provided with: a first power-on-reset circuit (PORa); a second power-on-reset circuit (PORb) that consumes more electricity and has higher reset voltage accuracy than the first power-on-reset circuit; a recording unit (28) that records information for setting the second power-on-reset circuit (PORb) to maintain an active state or set to an inactive state; and a central processing unit (CPU) which is initialized according to the output of the first and second power-on-reset circuits (PORa, PORb), and which sets the information in the recording unit (28).
