- if the MSB of an enabled scale becomes true and the value of the interrupt level is
different from 0:
{
- it requests interrupt by driving an interrupt request line IRQ1..7 low according to the
LEV<2..0> value;
- during the following acknowledge cycle it places on the VME data lines D00..D07 the
STATUS/ID; it is the byte contained in the 8 LSB of the Interrupt vector register
(address Base +% 04);
}
- if a VME MASTER accesses (read or write) the address Base +% 0C (Clear VME interrupt) it
releases its VME interrupt request line;
- if a VME MASTER accesses (read or write) the address Base +% 50 (Clear Scales):
{
- it releases its VME interrupt request line;
- it clears all the scales;
- it disables the VME interrupt generation;
}
