发明名称 COMMUNICATION CONTROLLER
摘要 <p>PURPOSE:To obtain a communication controller having an improved processing performance and a highly accurate timer function, by using properly the several types of interruption timers under the control of a communication control program CP. CONSTITUTION:A service processor SVP14 transfers the information including the types of times used by the hardware to a control program CP at the initialization of the CP. Thus the CP performs the initialization according to the received information on the initialization and is set under an operation state. Here the CP delivers an instruction to the SVP14 for the request of the timer type if no coincidence is obtained between the type of the timer used by the hardware and the type desired by the CP. Then the SVP14 performs the control for the change of the timer type to a central processing part CCU10 including a timer interruption mechanism in response to the instruction given from the CP. Then the SVP 14 informs the end of this processing to the CP. Hereafter the CP can receive the interruption of its desired timer from the CCU10.</p>
