  • Bit 4: Auto-int 5 (programmable timer, see 600017)
  • Bit 3: Auto-int 4 (link port)
  • Bit 2: Auto-int 3 (USB port on Titanium, OSC2/2^19 on HW2)
  • Bit 1: Auto-int 2 (keyboard)
  • Bit 0: Auto-int 1 (OSC2/2^11)

Auto-int 6 (ON key) always wakes the CPU. Auto-int 6 must be acknowledged before writing to this port. (see 60001A)
