clarification on External interrupt of SPC560P-DISP Discovery board

[RatheeshT]

Hi Technical Team,

I have SPC560P-DISP Discovery board which is based on the 32-bit microcontrollers Power Architecture® Core SPC560P50L5. For programming this board, i am referring "RM0022 Reference manual"( revision history of document : Revision - 8 and Date :10-Jul-2015). SPC560P-DISP Discovery board has 32 external interrupt only (Table : 99 (EIRQ[0:31]) in reference document ). But i need to configure 80 input resources as external interrupt. 

My question are

1. How can i directly configure 80 input resources as external interrupt?

2. If it is not possible for 80 external interrupts, what is the alternate solution for this?

Please provide your input to proceed my development work.

Hello ,

I think that , you need an additional hardware to configure 80 input resources as external interrupt ?

Best regards
