Abstract
PURPOSE:To eliminate the need for processing for setting data from a CPU side and to speed up connection processing by storing relay connection data in a ROM previously and reading out necessary connection data. CONSTITUTION:Respective data of the ROM 11 accessed in order by an address counter 10 are outputted to latch circuits 12a-12k in order and latched. Then the counter 10 accesses the ROM up to an address set as stop address data in a register 17 previously and then stops operating. The ROM 11 is stored with data for driving drivers 13a-13m in order as (k) addresses corresponding to the number (k) of the latch circuits as one connection unit according to the connection state of an S/P. Consequently, the ROM 11 is only accessed by the counter 10 to control the connection state of relays, and a control speed is increased almost to the generation speed of the clock signal CK of a clock generating circuit 15.
