PIB interrupts | Cypress Semiconductor
I have a design with a USB OUT sending data to a p-port consumer. Its in auto dma mode. I decided to add the PIB interrupt code from the Designing with the EZ-USB® FX3™ Slave FIFO Interface app note to check that there are no errors. When I ran the design I am getting CYU3P_PIB_ERR_THR0_RD_UNDERRUN errors. The thing is I am not using thread 0 as the consumer is on thread 3. Anyone know why this would occur?
