Interrupt EnableDisable in Microblaze Port Posted by neilabc on November 25, 2017 Yes, those bits are in the Xilinx interrupt controller driver, which is called from the RTOS code.The MicroBlaze configuration parameters CINTERRUPTISEDGE and CEDGEISPOSITIVE defines this behaviour. So you need to configure MicroBlaze so that it matches with your interrupt signal. The default settings are risingedge triggered which works with most interrupt sources. micro blaze interrupt controller driver
For interrupts, MicroBlaze supports only one external interrupt source (connecting to the Interrupt input port). If multiple interrupts are needed, an interrupt controller must be used to handle multiple
It is the responsibility of the application get the interrupt handler of the ATM controller and connect it to the interrupt source. The driver services interrupts and passes ATM cells to the upper layer software through callback functions. micro blaze interrupt controller driver
