Keystone interrupt

Johannes
Mastermind 6240 points

Hi,

I was looking at the interrupts for 6657 and I saw these interrupts:

164 UARTINT_A UART_0 interrupt
165 URXEVT_A UART_0 interrupt
166 UTXEVT_A UART_0 interrupt

167 EASYNCERR EMIF16 error interrupt

What exactly do they do? I searched in the related manuals but I didn't find anything.

They're not described anywhere. These interrupts are commom to the Keystone devices, not only 6657

I didn't looked at all interrupts but I think that there are more that are not explained. Is there a way to know exactly how they work?

Thanks

    Johannes,

    The description for these signals in the data manual are not a lot of help, but they at least point you to the correct module so you can read more about the signals.

    Both the UART and EMIF16 User Guides have sections titled "Interrupt Support" which explain the function of the single interrupt signal that is supplied by each.

    The description in the data manual for the UxxEVT signals is misleading due to our interchanging the term "event" and "interrupt". You can search the UART User Guide for URXEVT to find the description of the use of these two signals, or scroll down to the next section after reading about the UART Interrupt in the "Interrupt Support" section.

    We could do better in our documentation, but the information is there after requiring you to make some assumptions about what we meant to say. We apologize for the inconvenience it has caused you and hope that this will help you with tracking down the information for other signals in the device as they come to your attention.

    Regards,

    Hi Randy,

    I saw the interrupt sections in those documents but I was not sure if the signals in the User guides and in the datasheet were the same.

    Thanks for clarifying that.

    Regards
