For active supply current measurements all ports are configured in quasi-bidirectional mode.
Timers 0, 1 and 2 are configured to be free running in their default timer modes. The CPU exe-
cutes a simple random number generator that accesses RAM, the SFR bus and exercises the
ALU and hardware multiplier.
