+See the top level README for information on where to find the
+schematic and programmers reference manual for the ARM processor
+on the raspberry pi.
+
+This example uses the free running ARM timer, not the 64 bit system
+one as in blinker02 but the so called ARM timer.
+
+The system clock appears to come up at 250MHz as documented.  Divide that
+by 250 to get 1Mhz on this free running ARM timer.  Then count to four
+million ticks between led state changes and the led will change state
+every four seconds.
