Abstract:
1. A PHS terminal device comprising: a receiver that receives a time slot containing PHS data including a unique word; a first checking mechanism that executes a first check to determine detection of said unique word upon receipt of said time slot by said receiver and that outputs a first interrupting signal upon said first check indicating detection of said unique word; a first starting mechanism that starts a first interrupting routine in response to said first interrupting signal; a first storing mechanism that stores a result of said first check in a first software flag during said first interrupting routine; a second checking mechanism that executes a second check to determine completion of reception of said time slot and that outputs a second interrupting signal upon indication of completion of reception of said time slot responsive to said second check; a second starting mechanism that starts a second interrupting routine in response to said second interrupting signal; a first confirming mechanism that confirms said result of said first check by confirming said first software flag during said second interrupting routine; a processing mechanism that executes data processing of said time slot according to a confirmation result of said first confirming mechanism during said second interrupting routine, said time slot further includes CRC data; a third checking mechanism that executes a third check to check if a CRC error exists based on said CRC data; a second confirming mechanism that confirms a result of said third check; and an admitting mechanism that admits data processing by said processing mechanism based on a confirmation result by said second confirming mechanism, wherein said second confirming mechanism confirms a result of said third check before said second interrupting signal is output, and said admitting mechanism omits starting of said second interrupting routine when said CRC error is shown to exist as said confirmation result by said second confirming mechanism.
