MIAC CAN Interrupt

[QMESAR]

Hi Team.

Can you please help me ,is there anyway that I can link the MCP2515 CAN controller INT pin to one of the IOC pins on the Micro ,
in a busy application polling the CAN bus results in a loss of messages,

I am prepared to do the HW change myself but with out a schematic it is Risky affair

Which version of MIAC are you using?

Hi Leigh,

Sorry it is MIAC dsPIC V3 or something

[LeighM]

There are no spare inputs.
But you could link across to either (UART0 RX) Port E1, or (UART1 RX) Port E3
Assuming you don't require both UARTs
These are available if you remove the UART selection header link ...
