Abstract
When a request for reception of radio signals is delivered by wireless communication section 3, subordinate processing portion 12 fetches programs necessary for reception of radio data from external memory 2 and stores them into command cache memory 13. At this instant, to prevent data stored in command cache memory 13 from being altered by other interrupt requests, the system instructs interrupt controller 16 to mask all interrupt requests except urgent ones. Through this arrangement it is possible to reduce noise during execution of a specific processing, particularly during reception of data.
