Original question:

LP-AM243: Finding out which pin a GPIO interrupt was triggered on

AM2434: Maximum number of interrupts

Tomasz Krupski

Part Number: AM2434

Hi! 

Using 

adc_singleshot_am243x-evm_r5fss0-0_freertos_ti-arm-clang

and

mcu_plus_sdk_am243x_08_06_00_43

in the example.syscfg I was able to configure max. 8 interrupts with ROUTERs from 0 to 7. 

My question is:

What ist the maximum number of interrupts which can be implemented on AM2434BSFFHIALV and if >8 how it can be done? Will >8 interrupts be supported in the SDK?

In my application I need about 20 rising and falling edge interrupts.

    Hi Tomasz,

    The R5F VIM can handle up to 512 different interrupts. AM243x has 265 actual interrupts. See the R5FSS0_CORE0 Interrupt Map in TRM for details

    If you are talking about the interrupts with ROUTERs, there are 16 interrupts for MAIN GPIO router (MAIN_GPIOMUX_INTROUTER0_OUTP_0 - 15), 4 from MCU GPIO router (MCU_MCU_GPIOMUX_INTROUTER0_OUTP_0 - 3)

    Best regards,

    Ming
