Abstract
PURPOSE:To make it possible to confirm the writing of channel selection data visually by constituting a circuit that prolongs a memory write operation time of tens milliseconds to a time width of 2-3sec by providing an integrating circuit. CONSTITUTION:When channel-selection data write instruction pulse wr is output from microcomputer COM to semiconductor memory M for channel selection, memory controller CNT outputs write/read pulse P to memory M, so that write data WD from COM will be written in memory M at fixed addresses. Once pulse wr is output, this pulse of several milliseconds is integrated by capacitor C1 in display unit DP, and consequently display element LED stays on for the time width of 2-3sec that is long enough for visual confirmation.
