Abstract

PURPOSE:To shorten a rewrite time when high speed transmission is required, transmitting data of words continuously with transmission word counter locked, when high speed request signal is established. CONSTITUTION:On normal condition, transmitting counter 4 counts up in sequence, outputting data address signal to corresponding word to parallel and serial converter 5 to the transmitting format decroder circuit 3. When the control unit to be controlled, which requires high speed transmitting is selected by OR connecting contact points corresponded to unit selectting switch group 1, high speed transmitting freguest signal 7 is output to the transmitting counter 4 from transmitting ormat decorder circuit 3, transmitting counter address is locked. When the address is locked, data of the same address is transmitted until high speed tranmsitting request signal 7 is turned off.
