But it might not be for everyone. 5. Itll allow you to improve the sound you record instantly, give you access to layering your music, and will enable you to convert digital sound to analog sound. If the INTR interrupt is enabled, the 8086 will go through its INTR interrupt procedure and sends out two INTA pulses to both the master and the slave. Reference voltage for conversion is provided using +Vref and -Vref. When the slave receives an interrupt signal on one of its IR inputs, it checks mask condition and priority of the interrupt request. Sending the 3-bit ID number enables the slave. The INTA signal is connected to both master and slave 8259. (DAC) has to be employed. Clipping is a handy way to collect important slides you want to go back to later. As we are using single 8259 in the system SP/EN pin is tied high and CAS0-CAS2 lines are left open.
