Hardware SPI Continued - IO from Scratch - Part 7

This is the second half of the Hardware SPI video that would have been far too long. As such the beginning jumps strait into implementation, I usually try and start in a less sudden way.

In this video I add hardware support for the remaining two lines MOSI and the Clock and unlock sustained transfer speeds at the full clock rate of the cpu, 8 megabits per seconds!

I made a couple of tweaks to this circuit after main recording, these are both minor things in my original plan but there was a little more troubleshooting than I had expected and I passed these over in the main build. I added them here: https://youtu.be/pUjDu1qXBw0
