PURPOSE:To reduce a load on software by performing successive time control over a process output circuit, used for a word-serial bit-parallel system, through hardware, and interrupting a microprocessor. CONSTITUTION:A microcomputer device 6 consists of a microprocessor MPU7, a process output controller 8 which has a function of performing time control over RDY control and a transmission rate, and a clock pulse generator 9. The process output controller 8 consists of a clock counting circuit 10, an RDY control circuit 11, a command detecting circuit 12 for detecting a command signal outputted when the MPU7 writes information, a storage circuit 13 for the state wherein information is being outputted, a process output circuit 14 for outputting information, and an interruption generating circuit for causing an interruption a transmission time later. |
