PURPOSE:To reduce the mounting space and to simplify the hardware, by obtaining a counter output subjected to time division at each channel with an output latching a counter output stored temorarily in an RAM. CONSTITUTION:A channel designation signal fd is sent to a scanner 16 and an RAN 12 from a channel forming counter 20 with a timing signal TM1 issued from a timing circuit 18, and a scanner 16 outputs ''0'' or ''1'' to an ROM 10 by the presence of the counter input. Further, the ROM 10 produces a counter output as the firmware based on this signal and a feedback signal Inf. Then, the outpt of the ROM 10 is written in the RAM 12 with a timing signal TM3 and read out and then sent to a latch circuit 14. Then, the latch output of a circuit 14 outputs a counter signal P subjected to time division at each new channel. |
