Notes

  • The bits marked with '-' are not connected and give "1" on reading.
  • The registers $d01e and $d01f cannot be written and are automatically cleared on reading.
  • The RES bit (bit 5) of register $d016 has no function on the VIC 6567/6569 examined as yet. On the 6566, this bit is used to stop the VIC.
  • Bit 7 in register $d011 (RST8) is bit 8 of register $d012. Together they are called "RASTER" in the following. A write access to these bits sets the comparison line for the raster interrupt.
