-
- addr_len can take any value from 0-255, it is only limited

- 0 we skip the address write cycle.
-
- Typical case is a Write of an addr followd by a Read. The
- IBM FAQ does not cover this. On the last byte of the write
- we don't set the creg CHT bit, and on the first bytes of the
- read we set the RPST bit.
-
- It does not support address only transfers, there must be
- a data part. If you want to write the address yourself, put
- it in the data pointer.

- It does not support transfer to/from address 0.
