vbase
contains the base address of the 352-word vector table.
The VEC[3:0] signals are multiplexed with the BIO signals IOBIT[7:4] onto the VEC[3:0]/IOBIT[7:4] pins (VEC0 corresponds to IOBIT7, VEC1
corresponds to IOBIT6, VEC2 corresponds to IOBIT5, and VEC3 corresponds to IOBIT4). VEC[3:0] defaults to 0xF (all ones) if the core is not
currently servicing an interrupt or a trap.
§ The programmer specifies the relative priority levels 0—3 for hardware interrupts via
inc0
and
inc1
(see the DSP16000 Digital Signal Proces-
sor CoreInformation Manual). Level 0 indicates a disabled interrupt. If the core simultaneously recognizes more than one interrupt with the
same assigned priority, it services the interrupt with the lowest vector address first.
