* Attach Aux pin 1 to the signal to capture then *
* run the test, repeat the test and capture one or *
* more times to run the system clock and record the *
* state of pin 1. *
* *
* The returned state is a hexadecimal byte stream *
* from left to right, each comprising a bit stream *
* from left (bit 7) to right (bit 0). *

* e.g. 12 34 56 78 *
