* HAL2 internal addressing
*
* The HAL2 has "indirect registers" (idr) which are accessed by writing to the
* Indirect Data registers. Write the address to the Indirect Address register
* to transfer the data.
*
* We define the H2IR_* to the read address and H2IW_* to the write address and
* H2I_* to be fields in whatever register is referred to.
*
* When we write to indirect registers which are larger than one word (16 bit)
* we have to fill more than one indirect register before writing. When we read
* back however we have to read several times, each time with different Read
* Back Indexes (there are defs for doing this easily).
