// Clears the register to start from
known state
// Interrupt occurs in bit 301
// Query Status Byte Register
// Interrupt occurred but STB doesn't
see it yet
// Enable the bit so STB can see it
// Query STB again
// Now STB sees that an interrupt has
occurred
// Find out which interrupt source
// "1" means the interrupt source is
from bit 301
// Once read the event is cleared
// 0 now. If there is another interrupt, it
will be set to 1 again
