Abstract
A data processor is provided with a data input mode and a data output mode. The data input mode is set by an external signal. A serial data supplied from an external apparatus to a data input register has a signal to specify the start of the operation at its specific bit. The data processor is provided with a circuit which starts to operate by the operation start signal. This circuit generates an operation completion signal. Based on the operation completion signal, the mode of the data processor is automatically changed to the data output mode.
