After each test the content of the GPIO registers is checked against the expected values. The table results[] contains the number of mismatched bytes after each test.
Expected result: all bytes in results[] == 0x00
The compiled functions are executed in the simulator:

The first block of data is the content of the GPIO registers:
0x000 00 00 00 00 00 .....
0x005 00 00 20 20 00 .. .
0x00a 00 00 20 10 00 .. ..
0x00f 00 00 42 02 42 ..B.B
The next line contains the result bytes, one for each test step. Zero means no differences to the expected result:
0x0001 00 00 00 00 00 00 ......
The last block is a simple memory dump. It might contain additional information (but not used here and always zero):
0x0100 00 00 00 00 00 00 00 00 ........
0x0108 00 00 00 00 00 00 00 00 ........
