Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

Safe update of volatile multi-byte variables without disabling interrupts

	/*************************************************************************************************************
	There is a well known problem with reading multi-byte volatile variables atomically on an 8-bit system,
	ie an ISR could update the variable's bytes half way through a read, causing a corrupted value to be read.
	Standard solution is to disable interrupts during reads, but this could affect critical ISR response times.
	In the case of the 1ms timer interrupt, if two back to back reads produce different results, the timer
	_was_ updated by the ISR and hence either read may have been corrupted.
	However, in this case, a subsequent 3rd read performed within 1ms of the previous reads will not
	be updated (or corrupted) by the ISR, so we can return this 3rd read instead.
