Abstract
PURPOSE:To form the titled processor to be able to use any type of a bar code reader by reading the bit information of the data of the special address of an I/O port and recognizing the classification of the bar code reader. CONSTITUTION:When a bar code reader 4 is of a decoder built-in type, special data are prepared so as to return them through an RXD signal line in a constant time for the transmitting data from the VART 2, therefore, a CPU 1 confirms whether or not the data are sent from the bar code reader 4 to the VART 2 thus, the classification of the bar code reader can be decided. On the contrary, even when a constant time passage and an RXRDY bit is zero as it is, it is shown that the data are not returned from the bar code reader 4, and therefore, the CPU 1 can decide that a bar detecting type bar code reader is connected to CN. Thus, even the bar code reader of either of the types of a decoder built-in type and a bar detecting type can be connected and used to the same connector.
