Abstract

In a data processor including a serial interface, the serial interface internally includes a transmission end flag formed of a RS flipflop which set in response to the starting of the transmission of data of one byte and reset in response to completion of the transmission of the data of one byte. When the operation is changed from a macroservice processing for a serial data transmission to a vector interrupt processing, a CPU watches and discriminates the condition of the transmission end flag in a programmed operation of the CPU, thereby detecting a timing where data to be transmitted is transferred to a transmission shift register in the serial interface.
