| 摘要 |
<p>The present invention relates to a common interrupt generation/block apparatus wherein UART(Universal Asynchronous Receiver/Transmitter), a asynchronous series communication transmitter/receiver generates/blocks an interrupt signal generated in each UART of QUAD UART including 4 channels, or generate/blocks an interrupt signal line generated in each of 4 channels as one common interrupt signal line. That is, the present invention provides an interrupt signal control apparatus for receiving and transmitting a series of asynchronous information having 4 channels in which a common interrupt signal line which can be used commonly is generated by controlling an individual interrupt signal line by using a signal line of an interrupt transmission/block control means operated by an outside circuit, it is determined that the core portion of an UART where the signal line is generated, and after switching the polarity of the generated common interrupt signal line, an interrupt signal through which is to be connected to outside is selected.</p> |
