Title: Operating method for communication controller
Inventor: MAMIYA HIROSHI
IPC: H04L29/02
Filed: 1990-06-13
Abstract: PURPOSE:To prevent occurrence of data defect or communication fault by limiting the relation between a CPU section of a communication controller and a communication control section to data transmission reception only and adopting the interactive way between the both. CONSTITUTION:When a communication control section receives a data from a line, the data is stored in a buffer. Reception request information to urge data reception is sent to a CPU section 2. However, the received data is kept in the buffer because no reception enable reply comes from the CPU section 2. A reception request is sent again for each prescribed time and the operation restart of the CPU section is awaited. When the operation of the CPU section 2 is restarted, the communication control section confirms the reception enable reply and normal operation is attained. Since the communication control section is operated independently even when the CPU section 2 is stopped, the communication protocol processing with a line is processed normally.
