MSP430G2553: MSP430 Interrupt number

Part Number: MSP430G2553

Hi,

using an MSP430G2553 with a USART-Connection, i experience a permantent interrupt, which makes the program to halt.

Providing the programm with all the interrupt service routines that exist, i found, that interrupt 6 is the source.

My question is: what is the interrupt nr. 6? I searched in several Websites, but found no answer.

Yours Mathias

    __interrupt_vector_6 : { KEEP (*(__interrupt_vector_6 )) KEEP (*(__interrupt_vector_adc10)) } > VECT6

    Thanks for the answer to my question!

    But this does not solve the problem.

    When changing interrupt6 to ADC10_VECTOR as shown below, the program loops again in the "#pragma vector=unused_interrupts" routine.

    So interrupt6 must be something different.

    Is there a document, where the assignation between an interrupt source to the interrupt number can be seen?

    #if 1
    #pragma vector=ADC10_VECTOR
    __interrupt void ADC10_vector (void) {
        _bic_SR_register_on_exit(CPUOFF);       // wake up...
    }
    #else
    #pragma vector=6
    __interrupt void interrupt6 (void) {
        _bic_SR_register_on_exit(CPUOFF);       // wake up...
    }
    #endif

    The problem is solved. Interrupt number 6 It is the interrupt vector USCIAB0TX.

    Now i can go on to bring the program to run.

    Thanks for your support!

    An off by one thing. Either your particular compiler counts the vectors from zero or it is old enough that it doesn't include the TRAPINT vector. (See USCI29 errata.)
