SPI: Clear error flags when detected #14

Open austinglaser opened 6 years ago

austinglaser commented 6 years ago

Closes #13

This implements the first option (automatic clearing errors on detection) discussed in the above issue. It hasn't yet been tested on actual hardware -- I likely won't be able to do so until this weekend.

The biggest stumbling block I see for testing is actually causing the errors. An overrun should be easy to force, and probably a mode fault. I'm not sure how to force a crc error though...

Made an update to how the MODF error is cleared to ensure that the exact sequence of register accesses called out in the reference manual is followed

Any updates on this?
