Programmer’s guide
The base set of registers that is used during high-speed data transfer have a
straightforward access method. The extended function registers require special
access bits to be decoded along with the address lines. The following guide will help
with programming these registers. Note that the descriptions below are for individual
register access. Some streamlining through interleaving can be obtained when
programming all the registers.
