Logic analyzer setup
--------------------

The logic analyzer used was a CWAV USBee SX (at 8MHz):

  Probe       93LC46B pin
  -----------------------
  0           CS
  1           CLK
  2           DI
  3           DO
  4           ORG

The ORG pin is tied high to use the x16 memory organisation (16-bit words).
