+== General ==
+The '''o'''ne '''t'''ime '''p'''rogrammable memory is used to store 32 4byte words. It is programmed sometimes during the factory process and can never be changed afterwards. Next to the Wii's shared and public keys it also contains a random number generation seed and the boot1 hash which basically makes it impossible for us to change boot1.
+== Register List ==
+{{reglist|Hollywood GPIOs}}
+{{rla|0x0d8001ec|32|HW_OTP_COMMAND|OTP command}}
+{{rla|0x0d8001f0|32|HW_OTP_DATA|OTP data}}
+|}
+== Register descriptions ==
+{{regsimple|HW_OTP_COMMAND|addr=0x0d8001ec|bits=32|access=R/W}}
+This register contains the command sent to the OTP. Reading data is 0x8000_00aa where aa is the address of the 4byte word you want to read. It is unknown whether is register is also used during the factory process to program the OTP.
+----
+{{regsimple|HW_OTP_DATA|addr=0x0d8001f0|bits=32|access=R/W}}
+This register contains the output data for the last issued OTP command. Changes of the HW_OTP_COMMAND register directly change this register without any delays.
+----
+== OTP Contents ==
+The following things are stored inside the OTP:
