PURPOSE:To attain ease of change in a processing procedure and also to attain high speed real time processing by providing a serial data read control circuit and a serial data write control circuit so as to execute continuously a command. CONSTITUTION:The serial data read control circuit RSC50 consists of a programable logic array PLA30 and an FF8 and the serial data write control circuit WSC60 consists of a PLA17 and an FF16. In starting the RSC50, a main control circuit MC1 issues a serial data processing command to a command register 4 and in starting the WSC60, a write command is issued to a command register 12. When the RSC50 executes the command issued continuously by the MC1 and completes it in this case, the completion is reported to the MC1 and also the WSC60 executes continuously the given command by transmitting a signal to the WSC60. Thus, the change in the processing procedure is attained easily and high speed real time processing is conducted. |
