12. Registers 12.2.63 VME Interrupt Map 1 Register (VINT_MAP1) This register maps VMEbus interrupt sources to one of the seven VMEbus interrupt pins. A value of 001 maps the corresponding interrupt source to VIRQ*[1], a value of 010 maps to VIRQ*[2], etc. A value of 000 effectively masks the interrupt since there is no corresponding VIRQ*[0]. SW_INT is set to 010 with the VME64AUTO power-up option.
