Abstract

PURPOSE:To pick up processing data independently of ISO code input and EIA code input and to unify the data processing control afterward, by storing a final processing data corresponding to the address to a register. CONSTITUTION:A tape reader 6 is started from a microprocessor MP3 via an IOC decoder 4, ODER decoder 5, and FF9, and 8 channel data is set to a data latch 7. At the same time, the MP3 fetches data via an input multiplexer 8 to check if the data is coincident with the content of a buffer register 2 for an odd or even number. If coincident, the fetched data is given as the address of a data storage register 1, allowing to obtain the specified processing data independently of the ISO, EIA codes.
