You need the technical manual rather than the user manual. You can
either talk directly to the hardware using the 4 addresses $C0m0..C0m3
(the first 3 are a 20 bit address and the last byte is a data port -
each time you read or write the data port the address auto-increments.
Alternatively, you can use the SmartPort interface and use the READ and
WRITE commands (to either Main or Aux RAM).
