Copper Data 8-bit Write Register

Number	TBRegisterNumber::$60
Readable	TBRegisterReadable::No
Writable	TBRegisterWritable::Yes
Short Description	[[ShortDesc::Used to upload code to the Copper.]]

After the write, the index is auto-incremented to the next memory position. The index wraps to zero when the last BYTE of program RAM is written (position 2047).

Each Copper instruction is composed by two bytes (16 bits) - two writes are required to complete one instruction upload.
