R/W

Read/Write

R/W = 0. Write memory.

Address bits are provided by the Destination Register (DST)

Data bits are provided by the Source Register (SRC)

R/W = 1. Read Memory.

Address bits are provided by the Destination Register (DST)

Data bits will be in Source Register (SRC) when BUSY (Status Register) will go to ”0”.

Command memory.

CM = 1 Access to Command Memory

CM = 0 Access to Auxiliary Memory.
