How to disable all UART error interrupts?

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

Alex

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
