Access in a demultiplexed P-interface mode:
Read/write, address:
Reset value:
MA7..0
If the value MA(10:0) is used as a control memory address, each address corresponds
to a single output time slot (see table 12):

Note: Port(m) means, that this port drives the inverted data values of port (m-8). For the
operation “Read Data Memory” MA10..0 are used as data memory addresses with
the same mapping to the input time slots as listed in the above table.
