MSC8101 to MSC8102 Interrupt Connectivity
The FPGA is used to route the interrupts/GPIO lines between the MSC8101 and MSC8102s. For
flexibility the MSC8101 has 5 GPIO lines (PC4, PC5, PC24, PC25 & PC30) connected to the FPGA
and in turn receives 7 IRQ inputs from the FPGA. Each MSC8102 has GPIO30 and INT_OUT
connected to the FPGA, with their respective IRQ1 and IRQ2 also connected, Figure 7. The standard
pre-programmed FPGA interrupt routing is shown in Figure 8.
