    pdegli
    Hello, you can find good hints on how to save the CPU registers while servicing an interrupt in the CPU and instructions reference manual (spru430) and peeking into the assembler code generated by the C compiler when you declare a function using the interrupt keyword. Main registers are "hardware...

    Jon I would like to install an ISR that resets the UART if any physical errors are detected (I would prefer not to poll the error bit). There is a bit called RX_ERR_INT_ENA in SCICTL1, but I don't see a vector for it in the PIE vector table ( 6.3.4 The PIE Vector Table in SPRU078E). Does the error...

  • Forum Post: Re: TMS320f2812 default ISRs; best practices?

    Lori Heustess
    Jon, For INT1 to INT12, where it says they are not used, these locations are truely not used. Instead they are muxed interrupts in the associated PIE group. For example, PIE group 1 will be fed into INT1 so there isn't a single vector that corresponds to INT1. Instead you use the vectors in PIE...

    Great advice, but the question remains: the IFR only has 16 bits. How do you acknowledge interrupts 16-31?

  • Forum Post: Re: TMS320f2812 default ISRs; best practices?

    BrandonAzbell
    Those particular interrupts are defined as Non-maskable interrupts and are described in Section 3.5 of the TMS320C28x DSP CPU and Instruction Set Reference Guide ( SPRU430 ) . The software interrupt instructions and /NMI are associated with this. The C28x immediately approves this type of interrupt...

There is a vector table of 128 PIE vectors defined in the linker script like this: .vectors: > PIE PAGE 1 SPRU078E defines this in table 6.4. The first 32 vectors are for core interrupts...
