AUXILIARY MEMORY ACCESSES: CM=0

Write Auxiliary Memory: Transmit command / indicate channels

CMD and SRC registers are written if their bits have not the right value.

CMD and SRC registers can be written in any order.

DST register is always written the last.

Read Auxiliary Memory in two steps: Transmit command / indicate channels

First step: register writing:

CMD register is written if its bits are not the right value.

SRC register is not written.
