Interrupt management: sbd_intr_o and pmt_intr_o generation
The Ethernet MAC provides two interrupt lines to VIC (Vectored Interrupt Controller):
●
sbd_intr_o: general interrupt signal connected to the VIC IRQ 56 line;
●
pmt_intr_o: interrupt signal generated from PMT (Power Management) module
connected to VIC IRQ 55 line;
