MPC5668G, interrupt on PA0 pin?

Hi,

I am trying to install an interrupt on the pin PA0(with the pad number 0).

But interrupt for this pin doesn't seem to be generated.

I have enabled the corresponding pin of IREER , IFEER , DIRER and using the Vector number 53(from the manual)?

Can you please support me by suggesting if I am missing any additional configurations?

Or if available ,Please attach the example code in which PA0  state is used for for generating an interrupt.

Regards,

Sukruth

Hi Sukruth,

PA0 cannot be selected as the source for a IRQ0 line, just PB0, PC0, PD0, PE0, PF0, PG0, PH0, PJ0, PK0 can be used depending on setting of SIU_ISEL1[ESEL0], SIU.ISEL2[ESEL0] and SIU.ISEL2A[ESEL0] registers setting.
