66AK2H14: 66AK2H14 Interrupt Pins

joe lindula

Part Number: 66AK2H14

Hello, wanted to verify with the forum members the external interrupt pins for the 66AK2H14 processor. Looking on page 97 on the datasheet it looks like the following GPIO pins 8,9,10,11, and 12 are interrupt pins. If this is the case are there any strapping pins that I need to set in order to use GPIO_8 as an interrupt? I'm using a 1553 Transceiver on my board and want to tie its IRQ interrupt pin to the DSP to indicate that data has been received.

Thanks,

Joe

Hi Joe,

If not used for anything else gpio pins can be connected to external interrupts coming to the DSP.
This is not limited to GPIO pins 8, 9, 10, 11 and 12. It is a matter of programming the gpio and your application. In linux for example you can set the gpio as external interrupt source using gpio_to_irq() and dts configurations.

Best Regards,
Yordan
