How to disable all UART error interrupts?

[asfarley]

I'm getting UART overrun and framing errors in my application. I'd like to disable the UART error interrupts but I'm having trouble getting that to work. This is on a K22 MCU.

I've been using PE-generated code, so for UART I'm using ASynchroSerial components with lower-level ASerialLDD components. Within the ASerialLDD init function, I've replace the interrupt-enable line with interrupt-disable:

Previously was:

UART_PDD_EnableInterrupt(UART5_BASE_PTR, ( UART_PDD_INTERRUPT_RECEIVER | UART_PDD_INTERRUPT_PARITY_ERROR | UART_PDD_INTERRUPT_FRAMING_ERROR | UART_PDD_INTERRUPT_NOISE_ERROR | UART_PDD_INTERRUPT_OVERRUN_ERROR )); /* Enable interrupts */

Modified to:

UART_PDD_DisableInterrupt(UART5_BASE_PTR, ( UART_PDD_INTERRUPT_RECEIVER | UART_PDD_INTERRUPT_PARITY_ERROR | UART_PDD_INTERRUPT_FRAMING_ERROR | UART_PDD_INTERRUPT_NOISE_ERROR | UART_PDD_INTERRUPT_OVERRUN_ERROR ));

However, my code is still ending up in PE_ISR(Cpu_ivINT_UART5_ERR) when it gets framing errors or overruns. 

How can I *completely* disable these interrupts?

Thanks

Hi Alexander,

Please check the value of UARTx_C3 to ensure these Error Interrupt are disabled.

Here is the Interrupt vector assignments, you can also check if the UART error sources is disabled in NVIC.

Best Regards,

Robin
