 Block 10: Set up the constant limits to
perform the second test.
 Block 11: If block 10 fails, drive line 1
high.
 Block 13: Set up the constant limits to
perform the third test.
 Block 14: If block 13 fails, drive line 2
high.
 Block 16: Set up the constant limits to
perform the fourth test.
 Block 17: If block 10 fails, drive lines 1
and 2 high.
 Block 19: If block 10 fails, drive line 3
high.
 Block 20: Delay for 1 ms
 Block 21: Set all digital lines low.
 Block 22: Send out a notify event to
indicate that the test has ended.
 Block 23: Return to block 2 23 times.
