PURPOSE:To enable an immediate shift to a program corresponding to the transmission instruction of a remote control, by providing plural registers which can transfer a data to a program counter. CONSTITUTION:The length deciding result between pulses of the remote control transmission signal is held at the registers 3 and 4 respectively with every prescribed bits. The held data is transferred to a program counter (PC)2. The address corresponding to the data transferred to the PC2 of an ROM1 holds a program which executes an action corresponding to the remote control transmission signal. Thus this program is executed. Therefore it is not necessary to decided each received data unlike the conventional case. This can decrease the number of ROM steps, and at the same time a program can be changed to an optional address in a short time. |
